Permaculture Plants: Aronia or Chokeberry

Aronia, or Chokeberry, is a great shrub for the Forest Garden
Black Chokeberry (Aronia melanocarpa)

Common Name: Aronia, Chokeberry
Scientific Name: Aronia species
Family: Rosaceae (the Rose family)

Red Chokeberry (Aronia arbutifolia)

Species: 
  • Red Chokeberry (Aronia arbutifolia) - Large Shrub, Red Fruit
  • Black Chokeberry (Aronia melanocarpa) - Small to Medium-sized Shrub, Dark Purple-Black Fruit
  • Purple Chokeberry (Aronia prunifolia) - natural hybrid of Red and Black Chokeberry, but is now likely its own species

Black Chokeberry (Aronia melanocarpa)

Description:
The North American shrub known as Chokeberry had an extreme makeover once its nutritional profile was discovered. High in vitamin C and antioxidants, it is being touted as the healthiest fruit in the world. This new "superfood" was re-branded as Aronia (its scientific name), and it is now a common addition to juices and other health snacks. Typically a bit too astringent to eat raw, hence the original name, the fruit can easily be used in jams and jellies and even wines. It can also be made into syrup and tea. In the Forest Garden, it will attract beneficial insects, can withstand periods of drought, can be used as a windbreak and fruit-bearing hedge, and is strikingly beautiful most of the year.

Red Chokeberry (Aronia arbutifolia) by Mary Walcott, 1925

History:
The Aronia species are native to eastern North America. They have likely been used for thousands of years by natives for food and medicine. They have been used for some time as ornamentals, but it is only recently that they have become significantly more popular once they gained "health food" status.

Trivia:
  • The common name "Chokeberry" was given because, when raw, the fruit is typically too astringent (drying or mouth puckering). Many birds will avoid this berry until all other fruit sources are gone. This will often leave the fruit on the plants through mid-Winter.
  • The Aronia (aka ChokeBERRY) should not be confused with Prunus virginiana, the ChokeCHERRY, although fruits from both similar-looking plants are edible.
  • The fruit of Aronia is very high in vitamin C and antioxidants (specifically anthocyanins found in the Black Chokeberry (Aronia melanocarpa).
  • A mature plant can have up to 40 canes per shrub.

Chokeberry Jam

USING THIS PLANT
Primary Uses:
  • Edible fruit - usually cooked. Some improved varieties are mild enough to be eaten raw (see Trivia above).
  • Preserved Fruit - jams, jellies, preserves, etc. (naturally high in pectin). Can also be dried and used in teas and pemmican.
  • Fruit Juice - if mixed in a 1:1 ratio with another juice that is naturally sweet (like apple juice), then no other sweetener is needed
  • Juice can be reduced with heat to make syrup.
  • Primary or adjunct flavor in wines, but likely could be used in beers and liquors.
  • Tea Plant (dried fruits are used)
  • Fruit Leather

Secondary Uses:
  • General insect (especially bees) nectar plant
  • Wildlife food plant, especially birds, in Winter
  • Wildlife shelter plant for small mammals and birds
  • Groundcover plant - Black Chokeberry (Aronia melanocarpa), plant 3-4 feet (1 meter) apart
  • Ornamental Garden Plant
  • Drought-Resistant Plant - can withstand low water periods, but not extremely prolonged dry periods.
  • Windbreak species
  • Living Fence species

Yield: This varies dramatically on age, variety, and growing conditions, but a mature plant can average 22 lbs (10 kg) per year. Reports of almost 40 lbs (17 kg) per bush have been reported.
Harvesting: Autumn. Only harvest when fully ripe. Taste is better after a frost. A berry comb will greatly assist harvesting the small fruits.
Storage: Best when used fresh. Can be stored in a cool place (like a refrigerator) for up to two weeks.

Aronia can be used as a hedge or windbreak...

  • Red Chokeberry (Aronia arbutifolia) - Zone 4-9
  • Black Chokeberry (Aronia melanocarpa) - Zone 3-8
  • Purple Chokeberry (Aronia prunifolia) - Zone 4-7

AHS Heat Zone:
  • Red Chokeberry (Aronia arbutifolia) - Zone 8-4
  • Black Chokeberry (Aronia melanocarpa) - Zone 8-1
  • Purple Chokeberry (Aronia prunifolia) - Zone 8-1 

Chill Requirement: Likely, but no tested information is available; however, some studious amateurs suggest 800-1,000 chilling hours/units are needed for good flowering.

Plant Type: Shrub
Leaf Type: Deciduous
Forest Garden Use: Shrub Layer, Groundcover Layer
Cultivars/Varieties: Multiple varieties available

Pollination: Self-Pollinating. Pollinated by insects.
Flowering: Spring-Summer (May-June)

Life Span:
Years to Begin Bearing: 2-3 years
Years of Useful Life: No good information available, but this plant freely suckers. As one plant is starting to decline, a suckering plant can be established to take the original plant's place in the garden and in production.

Red Chokeberry (Aronia arbutifolia)


PHYSICAL CHARACTERISTICS OF THIS PLANT
Size: 
  • Red Chokeberry (Aronia arbutifolia) - 6-13 feet (1.8-4 meters) tall and 3-9 feet (0.9-3 meters) wide
  • Black Chokeberry (Aronia melanocarpa) - 1.5-6 feet (0.4-1.8 meters) tall and 6-10 feet (1.8-3 meters) wide
  • Purple Chokeberry (Aronia prunifolia) - 6-9 feet (1.8-3 meters) tall and 3-8 feet (0.9-2.5 meters) wide

Roots: Fibrous with the ability to sucker (send up shoots from underground roots)

Growth Rate: 
  • Red Chokeberry (Aronia arbutifolia) - Slow
  • Black Chokeberry (Aronia melanocarpa) - Slow to Fast (depending on environmental factors)


These shrubs can be quite prolific!


GROWING CONDITIONS FOR THIS PLANT
Light: Full to partial sun
Shade: Tolerates moderate shade, but fruit production is lower
Moisture: Can grow in wet to dry soils
pH: prefers acidic to neutral soil (5.1 - 6.5), but can grow in a wide range (5.0-8.5)

Special Considerations for Growing: 
  • Consider growing an improved variety for more or larger fruits.
  • Aronia does not tolerate juglone (a natural growth inhibitor produced by Black Walnut and its relatives). Consider using another plant as a buffer between your walnuts and Aronias.

Propagation: 
Usually from seed. Needs 12-13 weeks cold stratification for germination. Can be propagated from cuttings of half-ripe wood in Summer (cut one half inch below a node). Can divide suckers in late Autumn and Winter when the plant is dormant.

Maintenance:
Minimal, but will need to cut back suckers if not wanted. Also, thinning older canes once every few years will keep the plants more productive.

Concerns:
Red Chokeberry (Aronia arbutifolia) can sucker a bit more aggressively than the Black Chokeberry (Aronia melanocarpa); however, these are rarely invasive.

Free Plant Guilds E-Book from Midwest Permaculture


The team over at Midwest Permaculture has been doing some great work lately, and this free eBook on Plant Guilds is great! If you are unfamiliar with the concept of guilds, you can read my article on Permaculture Guilds.

This eBook is a great resource for Permaculture in a Temperate Climate... so, of course, I had to share it!

Permaculture Plants: Asian Pears

The Asian Pear is quite different than its European relative.

Common Name: Asian Pears
Scientific Name: Pyrus species
Family: Rosaceae (the Rose family)

Asian Pears can be russeted and light brown or clear and yellow.


Common Species:
  • Chinese Pear, Nashi Pear, Sand Pear (Pyrus pyrifolia)
  • Siberian Pear, Harbin Pear (Pyrus ussuriensis)
  • Chinese White Pear, Ya Pear (Pyrus x bretschneideris)

Description:
Asian Pears are not nearly as common in the West as their closely related cousin, the European Pear, but they are quickly gaining in popularity. They ­are typically round (apple-shaped), although the Chinese White Pear is more “pear”-shaped.  Asian Pears are more similar to an apple in texture and a cross between an apple and European Pear in flavor. They are at their best when picked ripe. All you need is to taste a perfectly ripe Asian Pear, and you will make room for it in your Forest Garden.

There are three types of Asian pears.

  • Round or roundish-flat fruit with green to yellow skin
  • Round or roundish-flat fruit with yellow to brown skin and bronze to gold russet (little dots)
  • Pear-shaped with green skin or brown skin and bronze russet 


History:
Native to the eastern Asia, specifically China, Korea, and Japan, Asian Pears are now grown throughout their native land as well as in Australia, New Zealand, and the United States.

Trivia:
  • Asian Pears are the oldest known cultivated pear.
  • Asian Pears contain enzymes that tenderize meat, which is why they are used in marinades.

USING THIS PLANT
Primary Uses:
  • Fresh eating – Asian Pears are more similar to an Apple in texture and a cross between an Apple and European Pear in flavor. Eat when fully ripe or it will be dry and hard. Great in salads.
  • Cooking – Asian Pears have a high water content, so they are not used identical to European Pears. They are great when used for marinating (see trivia below). Drier varieties may be used for cooking, baking, pies, tarts, etc., but they really are best cooked after they have been pureed. The crisp texture is not softened with cooking as with European Pears.
  • Sauces – In Asia, the pears are often ground and mixed into sauces instead of other sweeteners
  • Preserved – Preserves, Jams, Jellies, etc – will often need longer cooking times to reduce the high water content. Asian Pears dehydrate very well, and the dehydrated fruit can be used in many recipes for desserts or just eaten as is.

Secondary Uses:
  • General insect (especially bees) nectar and pollen plant
  • Wildlife food
  • Wildlife shelter
  • Primary or adjunt flavor component in beer, wine, cider, perry, mead, liquor, etc.
  • Can likely be Coppiced, although I can find no good reference for this.
  • Wood – Poles, posts, stakes, tools, crafts
  • Wood – Firewood, charcoal
  • Wood – Smoking/Barbeque: pear wood gives a soft “fruity” smoke to meats, similar to apple wood

Yield: Standard root stock – 3-8 bushels (105-280 liters) or 170-450 lbs (80-200 kg); semi-dwarf root stock – 1-2 bushels (35-70 liters); dwarf root stock – 1 bushel (35 liters) or 56 lbs (25 kg)

Harvesting: Late Summer to Autumn (August-October), but can vary based on variety and location. Pick when still crunchy (like an apple) and giving off a strong aroma – the strong and sweet fragrance of a ripe Asian Pear is the key to knowing when it is ripe. Softness is used to help determine ripeness in European Pears, but not Asian Pears.

Storage: Best when used right away, but can be stored for up to a month or more if kept in a cool, dry place and handled carefully to prevent bruising

Asian Pears will be covered in the beautiful flowers every Spring.

Siberian Pear (Pyrus ussuriensis)

Siberian Pear (Pyrus ussuriensis)

DESIGNING WITH THIS PLANT
USDA Hardiness Zone: Zone 4-9, but really depends on the species and variety
AHS Heat Zone: Zone 9-3, but really depends on the species and variety
Chill Requirement: 300-750 chilling hours/units depening on the variety

Plant Type: Small to Medium-sized Tree depending on the root stock
Leaf Type: Deciduous
Forest Garden Use: Canopy Layer, Sub-Canopy (Understory) Layer
Cultivars/Varieties: Many varieties available. (see my article about Asian Pear varieties)

Pollination: Asian Pears traditionally require cross-pollination, although a few varieties are self-fruitful. This requires two different varieties of Asian Pear. Some European Pears (Pyrus communis) will cross-pollinate Asian Pears. Because there is such a wide variety of pears and cross-pollination variations, it is best to get cross-pollination information from the nursery or catalog company you are purchasing your pears. Pollinated by insects.
Flowering: Spring (May)

Life Span:
Years to Begin Bearing: 3-7 years depending on the variety and rootstock
Years of Useful Life: up to 300 years. Dwarfing rootstocks live shorter lives

PHYSICAL CHARACTERISTICS OF THIS PLANT
Size:
  • Chinese Pear (Pyrus pyrifolia): 25-30 feet (7.5-9 meters) tall and 20-25 feet (6-7.5 meters) wide
  • Siberian Pear (Pyrus ussuriensis): 30-50 feet (9-15 meters) tall and 25-30 feet (7.5-9 meters) wide
  • Chinese White Pear (Pyrus x bretschneideris): 20-25 feet (6-7.5 meters) tall and 10-20 feet (3-6 meters) wide

Roots: Fibrous
Growth Rate: Medium

GROWING CONDITIONS FOR THIS PLANT
Light: Prefers full sun
Shade: Tolerates very little shade… shade is best avoided with pears
Moisture: Medium soil moisture preferred
pH: most species prefer fairly neutral soil (6.0-7.5), but many can tolerate a bit wider pH ranges

Special Considerations for Growing:
  • Pears to not tolerate juglone (natural growth inhibitor produced by Black Walnut and its relatives). Make sure you have other varieties of  trees and shrubs as a buffer between your walnuts and pears.
  • Pears are susceptible to Fire Blight, Pear Scab, and Canker, so try to choose varieties that are resistant to these diseases.
  • Make sure to consider flowering times when planning which varieties you choose. You need to make sure that you have compatible varieties (i.e. ones that will pollinate each other) flowering at the same time.

Propagation:
Named varieties are usually grafted because pear cultivars do not grow “true to type”, meaning that seeds will grow into trees that produce fruit that is likely to be nothing like the parent stock. If growing from seed, they will need 8-16 weeks cold stratification for germination. Less improved species and non-cultivars are often grown from seed.

Maintenance:
Typically, Asian Pears are pruned once a year to once every 2-3 years.

Concerns:
None

Permaculture Plants: Sorrel


A patch of wild Common Sorrel (Rumex acetosa

Common Name: Sorrel
Scientific Name: Rumex species
Family: Polygonaceae (the Buckwheat or Smartweed family)

It is easy to see why Sheep's Sorrel (Rumex acetosella) is also called Red Sorrel

Common Species:
  • French or Common Sorrel (Rumex acetosa
  • Sheep's, Red, or Field Sorrel (Rumex acetosella)
  • Monk's Rhubarb (Rumex alpinus)
  • Herb Patience (Rumex patientia)
  • Buckler-Leaved or French Sorrel (Rumex scutatus)


Buckler-Leaved Sorrel (Rumex scutatus) has a more spade-shaped leaf.

Description:
Docks and Sorrels are closely related species belonging to the Rumex genus. Most species are considered "weeds", but the ones listed here have a fantastically refreshing and bright flavor - think lemony lettuce! The flowers, seeds, and even roots are edible as well. They attract beneficial insects, mine for minerals in the soil, and are drought-tolerant to name but a few of their traits. An easy to maintain addition in the Forest Garden.

Common Sorrel (Rumex acetosa

Sheep, Red, or Field Sorrel (Rumex acetosella)

History:
There are over 200 species in the Rumex genus. Where these plants were not native, they were introduced on purpose or on accident, and they can now be found the world over. Only a few species of Sorrel have had much interest by plant breeders, so the wild plants are what we have.

Trivia:
  • "Sorrel" is also used to describe parts or tea from the Hibiscus which is popular around the Equator, but has no relation to the Rumex species
  • Sorrel is used fresh and cooked around the world in traditional cuisine most commonly in Europe, but also Africa and Asia
  • Sheep Sorrel was used to revegetate overgrazed fields in Australia

Sorrel is best picked when leaves are young and tender.

Common Sorrel (Rumex acetosa) - here's a recipe for soup:

USING THIS PLANT
Primary Uses:
  • Edible Leaves - unique fruity, sour (lemony) taste. Can be used raw (salads, on sandwiches, etc.) or cooked like spinach (soups, sauces, stews, pastries, spanakopita, quiches, etc.). The leaves may even be boiled to impart a lemony flavor to the water which is cooled and sweetened and used like lemonade.
  • Edible Flowers - typically used as a garnish for salads, but may be cooked as well.
  • Edible Roots - Some species have a large taproot which can be dried, ground, and used as a flour adjunct
  • Edible Seeds - May be eaten raw or cooked. May be dried, ground, and used as a flour adjunct

Secondary Uses:
  • General insect nectar plant
  • Dynamic Accumulator Plant - Excellent! (Potassium, Phosphorus, Calcium, Iron, Sodium)
  • Groundcover Plant
  • Pioneer Species - the deep roots can help break up hardened soils
  • Drought Tolerant Species
  • Juice from the leaves can be used to curdle milk
  • Juice from the leaves can be used to clean stains in clothing
  • Dye Plant - roots, leaves, and stems
  • Likely a decent feed plant for most domestic animals - chickens will eat the seeds (let them harvest themselves!) and greens sparingly

Harvesting: Spring harvest for leaves. Pick when young as older leaves are more fibrous.
Storage: Used fresh most commonly, but the leaves can be dried and used later.

Monk's Rhubarb is tolerant of cold climates, like alpine regions, hence its scientific name.
(Rumex alpinus

DESIGNING WITH THIS PLANT
USDA Hardiness Zone:
  • French or Common Sorrel (Rumex acetosa) - Zone 3-9
  • Sheep's Sorrel (Rumex acetosella) - Zone 1-9 
  • Buckler-Leaved Sorrel (Rumex scutatus) - Zone 3-9

AHS Heat Zone
  • French or Common Sorrel (Rumex acetosa) - Zone 6-1 
  • Sheep's Sorrel (Rumex acetosella): 10-1 
  • Buckler-Leaved Sorrel (Rumex scutatus) - Zone 6-1

Chill Requirement: No reliable information can be found

Plant Type: Herbaceous perennial
Leaf Type: Deciduous (some varieties are evergreen)
Forest Garden Use: Herbaceous Layer, Groundcover Layer
Cultivars/Varieties: Many species available. Some few have been improved.

Pollination: May be Self-Pollinating/Self-Fertile or Dioecious (male and female plants) depending on the species. Pollinated by wind.
Flowering: May-September

Life Span: No reliable information can be found, but as these plants reseed so easily, it is almost a moot question.

Sorrel's have small flowers that attract small, beneficial insects.
Sheep's Sorrel (Rumex acetosella)

While many species have taproots, all species have deep-growing roots.
Sheep's Sorrel (Rumex acetosella)

PHYSICAL CHARACTERISTICS OF THIS PLANT
Size: 
  • French or Common Sorrel (Rumex acetosa) - 12-36 inches tall and 12 inches wide
  • Sheep's Sorrel (Rumex acetosella) - 6 inches tall and indefinitely wide
  • Buckler-Leaved Sorrel (Rumex scutatus) - 12 inches tall and 12-24 inches wide

Roots: Deep and fibrous, some species have a taproot; Sheep Sorrel (Rumex acetosella) has stolons (stems called "runners" that grow along the ground and produce roots, and then new plants)
Growth Rate: Medium to Fast

While not its main use, Sorrels can produce a decent amount of seed.
Herb Patience (Rumex patientia)

GROWING CONDITIONS FOR THIS PLANT
Light: Prefers full sun
Shade: Most species tolerate light shade, although some can tolerate moderate shade
Moisture: Dry to medium-moisture soils
pH: can tolerate a very wide range of soils (3.5-8.5)

Special Considerations for Growing: None

Propagation: 
Typically, and easily, by seed - direct sow in Spring. Can transplant "wild" specimens. Can divide plants in Spring.

Maintenance:
None. Flowering will stop new leaf growth, so you can encourage young leaf growth by cutting off the flowering stem.

Concerns:
  • Poisonous - Leaves and contain oxalic acid. Large amounts need to be eaten for this to be toxic. When cooked, much of the oxalic acid is reduced.
  • Running types can be expansive - they can grow all over the place.
  • Many varieties of Sorrel reseed very easily, so some consider them a bit invasive... I see this as a great trait!

Permaculture Plants: Pecans and Hickory


Pecans... a favorite nut!

Common Name: Pecan and Hickory
Scientific Name: Carya species
Family: Juglandaceae (the Walnut family)

Hickory Nuts

Common Species:
  • Pecan (Carya illinoinensis) – large to very large tree
  • Shellbark Hickory (Carya laciniosa) – large tree
  • Shagbark Hickory (Carya ovata) – large tree
  • Hican (Carya x hybrids) – large to very large tree

Shagbark Hickory (Carya ovata)... Stunning!

Less Common Species:
  • Water Hickory (Carya aquatica) - large tree, used mainly for wood and fuel
  • Chinese Hickory (Carya cathayensis) - large tree, used for nuts, oil (nut), and wood
  • Bitternut Hickory (Carya cordiformis) - large tree, used mainly for wood and fuel
  • Pignut Hickory (Carya glabra) - very large tree, variable flavored nut, used mainly for wood and fuel
  • Mockernut Hickory (Carya tomentosa) - very large tree, good flavored nut but very tough shell, used mainly for wood and fuel 

A majestic Pecan tree

Description:
The Hickories and Pecans are large, slow-growing trees that can take many years to begin bearing. These majestic trees which give us some of the best tasting nuts, fantastic wood wood for smoking meat, and wood that can be used in a variety of ways, should be considered an investment for the future. I hope to enjoy, literally, the fruits of my labor, but I know my children, grandchildren, and maybe even my great-grandchildren will enjoy it as well.

Pecan (Carya illinoinensis) by Charles Sprague Sargent

History:
Native to Asia and North America, Hickories and Pecans have been used for food, wood, and fuel since people have been around to use them. These trees have been developed for larger and sweeter nuts, and the Pecans have had the most development so far.

Trivia:
  • The name “Hickory” comes from the Algonquian Indian (Native American people group) word pawcohiccora, meaning the nut from the Hickory tree.
  • Pecan and Hickory Nuts are not technically nuts… they are considered “drupes” or even "tryma". A drupe is a fruit with a single seed inside. So the “nut” of these plants have a soft fruit that dries and splits to reveal the seed… what we call the nut. A true nut is a fruit which forms a hard shell to cover the seed, and this hard shell (the fruit) does not split open on its own. Confused yet? It may be easiest to call it a nut!
  • “Papershell Pecans” are pecans that have such thin shells that the shell can be cracked by just squeezing together two nuts in your hand… some are so thin, that the shells can be cracked by just squuezing one nut between two fingers. However, these nuts are much more prone to cracking on the tree when the nut swells during heavy rains.
  • Pecans have nuts
  • Shagbark Hickory have nuts about 1.5 inches (4 cm) long
  • Shellbark Hickory have nuts about 2.5 inches (6 cm) long
  • The Hican is a cross between a Pecan (C. illinoinensis) and another Hickory species (Carya species)… so in reality, there are a wide variety of trees appropriately named Hican. Most hybrids have poor nuts, but the named Hicans typically produce very large and tasty nuts; although, they usually produce less nuts than either of its parents.
Pecan Pies would be reason enough to plant these trees.

USING THIS PLANT
Primary Uses:
  • Nut – Raw. Excellent taste in both Pecans and selected Hickories.
  • Nut – Cooked. Used in desserts, breads, baking, etc.
  • Nut – “Milk” can be made from Pecan nuts
  • Nut – Oil. An edible oil can be pressed from Pecans

Secondary Uses:
  • General insect pollen plant – attracts beneficial insects which feed on the pollen of these trees
  • Wildlife food
  • Wildlife shelter
  • Windbreak plant
  • Sap is edible (Hickories) – can be tapped like Maples and reduced (with heat) to make syrup. I have yet to try this syrup, but the reports on flavor I have found range from very good to fair and slightly bitter. Interesting.
  • Coppice Plant
  • Wood used for poles, posts, fence posts, stakes, tool handles (axes!).
  • Wood used for fuel (firewood), charcoal.
  • Wood is a great wood for smoking meats.
  • Dynamic Accumulator – Potassium and Calcium for all species; Phosphorus in Shagbark Hickory (C. ovata)
  • Biomass Plant – large tree with lots of leaf-fall every Autumn that can be left to decompose and build the forest soil, or it can be moved and used in other places or composted.

Yield: 
Highly variable on species and size of the tree. Hickories produce less than Pecans; Improved varieties often produce more than unimproved and wild species, although the hybrid Hican will produce less (but larger) nuts than the Pecan. 50 lbs (23 kg) is not uncommon for a 10-20 year old tree. Pecans can produce up to 100 lbs (46 kg) when they are 20-25 years old. A mature Pecan that is 75 years old or older can produce close to 500 lbs (225 kg) of nuts. There are some Pecans that have yielded over 1,000 lbs (450 kg) of nuts in a season!

Harvesting: Autumn. Although if you have Pecans in more warm locations, you may harvest all the way through January. Pecans and Hickory are typically harvested after they have fallen from the tree; however, some people (and commercial operations) use nets to catch the nuts during harvest season.
Storage: Can be used right away, but if the nuts are dried, they can store for a few years.

DESIGNING WITH THIS PLANT
USDA Hardiness Zone:
  • Pecan (Carya illinoinensis) – Zone 6-9
  • Shellbark Hickory (Carya laciniosa) – Zone 6
  • Shagbark Hickory (Carya ovata) – Zone 4-7
  • Hican (Carya x hybrids) – Zone 5

AHS Heat Zone:
  • Pecan (Carya illinoinensis) – Zone 9-1
  • Shellbark Hickory (Carya laciniosa) – Zone 8-1
  • Shagbark Hickory (Carya ovata) – Zone 8-1

Chill Requirement: 650-1,550 hours/units depending on the species/variety.


Plant Type: Large to very-large Trees
Leaf Type: Deciduous
Forest Garden Use: Canopy Layer
Cultivars/Varieties: A few very worthwhile species. There are quite a few cultivars and hybrids available.

Pollination: Self-Sterile (although a few varieties are self-fertile). Requires cross-pollination by other cultivars for the nuts to be produced. Pollinated by the wind. Trees can be pollinated by the wind carrying pollen from other trees up to 10 miles away!
Flowering: Late Spring to Early Summer.

Life Span:
Years to Begin Bearing: 3-10 years for Pecans (sooner in the south); 40 years for wild Hickories (only 3-7 years if the tree was grafted)
Years Between Major Cropping: 1-2 years
Years of Useful Life: minimim of 100 years, but most will be productive for at least 200 years. It is not uncommon for trees over 400 years old to still produce large yields.

Shagbark Hickory Nuts

How the Shagbark Hickory got its name...

PHYSICAL CHARACTERISTICS OF THIS PLANT
Size:
  • Pecan (Carya illinoinensis) – 75-120 feet (22-36 meters) tall and wide
  • Shellbark Hickory (Carya laciniosa) – 70-85 feet (21-25 meters) tall and 30-50 feet (9-15 meters) wide
  • Shagbark Hickory (Carya ovata) – 70-85 feet (21-25 meters) tall and 30-50 feet (9-15 meters) wide
  • Hican (Carya x hybrids) – 75 feet (22 meters) tall and 50 feet (15 meters) wide

Roots: Single, large taproot
Growth Rate: Slow. Some improved varieties grow at a bit faster rate than the wild species.

Shellbark Hickory (Carya laciniosa)
Check out this site for a great photo resource on Carya species: 

GROWING CONDITIONS FOR THIS PLANT
Light: Full sun
Shade: Some species tolerate light shade; the Shagbark Hickory (C. ovata) can tolerate a bit more shade than the other species. The Pecan (C. illinoinensis) doesn’t like any shade.
Moisture: Medium soil moisture preferred. The Shellbark Hickory (C. laciniosa) can tolerate more wet soils. The Shagbark Hickory (C. ovata) can tolerate some fairly dry periods and doesn’t like wet soils or flooding.
pH: most species prefer fairly neutral to alkaline soil (6.5-8.0)

Special Considerations for Growing:
  • Almost all of these trees are slow growing during their first few years.
  • Most species/varieties require a hot summer to thrive.
  • All species tolerate juglone (natural growth inhibitor produced by Black Walnut and its close relatives… Pecans and Hickories are more distant relatives of the Walnut). Consider using this tree as a buffer between your walnuts and other plantings.

Propagation:
From seed – needs at least 3 months cold stratification to germinate. If starting from seed, make sure to use deep pots to give room for the taproot. Get the seedlings into their permanent spots as soon as possible to avoid damaging or stunting that taproot. Ideally, if you can protect the seeds from mice, the seeds would be planted where you want the trees to grow. Named varieties are available from grafting.

Maintenance:
Very little. Once established, almost none.

Concerns:
Truly none. However, I have my own personal concerns about the grafted varieties. The majority of Pecans are grafted onto only a few rootstocks. Granted, these rootstocks are very hardy and resistant to many diseases, but I don’t like the idea of putting all my eggs in one basket. What if a disease came along that knocked out those few rootstocks? It is highly unlikely, but what if? My goal with my (future) forest garden is not to be a commercial producer of one thing (in this case, Pecans or Hickory Nuts). My goal is to create a bountiful and resiliant ecosystem. So what will that mean in practice? Well, I will certainly have a number of named varieties of Pecans on the standard rootstocks, but I will also likely grow some of my own trees from seed. This may delay the onset of nut production for many years, but I think it is a great legacy to leave. To know I planted something that my children and grandchildren will enjoy, even when I did not, sounds pretty great to me.

Permaculture Plants: Salal or Shallon

Salal is an evergreen shrub that fruits in shade! Awesome!

Common Name: Salal, Shallon
Scientific Name: Gaultheria shallon
Family: Ericaceae (the Heath or Heather family)

The small berries have a sweet, unique flavor that some say tastes like blueberries.

Description:
Salal is an evergreen understory shrub native to the West coast of North America. It has sweet, great-tasting berries that are reminiscent of blueberries. It is one of the few plants that fruit well in shade. It also attracts beneficial insects, feeds wildlife, can be used as a low windbreak or ground cover, and once established, it can tolerate drought. A great understory plant for the Forest Garden.

Gaultheria shallon

History:
Salal is a common understory plant, typically growing under conifers, and is native the the West coast of North America. It has been introduced in the UK where it has readily grown in more acidic environments. Some in Europe consider it a mildly invasive weed.

Trivia:
  • The name "salal" comes from the Chinnot Jargon sallal.
  • The name "shallon" come from the Native American (unsure which people group) shellwell.

Salal Preserves!

A couple more links to preserving salal berries:

USING THIS PLANT
Primary Uses:
  • Fresh Eating - fruit is like small blueberries
  • Baking - pies, tarts, turnovers, etc.  Use like blueberries or currants
  • Cooking - can be used in savory dishes
  • Preserves, jams, jellies, etc. The seeds are tiny (like strawberry seeds), so there is no need to strain them out
  • Dried fruit
  • Fruit Leather
  • Flavoring component to beers, wines, liquers, etc.

Secondary Uses:
  • General insect (especially bees) nectar plant
  • Wildlife food plant
  • Wildlife shelter plant
  • Groundcover plant - perfect for shady locations. Space about 3 feet (0.9 meters) apart.
  • Windbreak Shrub (very dense plant)
  • Hedge plant
  • Drought tolerant plant
  • Tea plant - from dried leaves
  • Edible leaves - young leaves are reportedly edible, but I have yet to try this
  • Salal is used in floral arrangements
  • Dye plant - fruit and leaves
  • Medicinal Uses

Yield: no reliable information can be found
Harvesting: Summer (July - August). Pick when the berries get dark and soft.
Storage: Like blueberries, will store fresh for about a week.

DESIGNING WITH THIS PLANT
USDA Hardiness Zone: 6-8
AHS Heat Zone: 8-6
Chill Requirement: 50-450 hours/units depending on the species and variety

Plant Type: Small to medium-sized Shrub
Leaf Type: Evergreen
Forest Garden Use: Shrub Layer, Groundcover Layer
Cultivars/Varieties: This plant has not been developed much

Pollination: Self-Pollinating/Self-Fertile. Pollinated by insects.
Flowering: April - June

Life Span:
Years to Begin Bearing: 2-3 years
Years of Useful Life: No good information available, but since this plant produces runners so easily, an individual plant's lifespan is not that important. An established community of Salal will live almost indefinitely.

The small berries have soft hairs on them - reminiscent of raspberries.

Salal berries will open as they mature.

Fully mature berries. Fruits are usually picked for eating before this stage.

PHYSICAL CHARACTERISTICS OF THIS PLANT
Size: 1-6 feet (0.3-1.8 meters) tall and indefinitely wide
Roots: Fibrous with stolons (aka "runners" - stems right at ground level that form roots)
Growth Rate: Medium

Salal makes a great groundcover for deep shade.

GROWING CONDITIONS FOR THIS PLANT
Light: Full sun to part shade
Shade: Tolerates deep shade
Moisture: Medium moisture soils
pH: prefers an acidic to fairly neutral soil (5.5-6.5), but can tolerate very acidic soils

Special Considerations for Growing: 
Salal has a combination of traits that let it fill a unique niche in the Forest Garden. A difficult spot to fill is often under conifers, but the acidic soil and shade is where Salal will thrive.

Propagation: Typically by seed - requires 4-17 weeks cold stratification (depending on the source of information). Can be propagated by cuttings or more commonly by splitting the new plants that develop from the runners.

Maintenance:
Takes a little care to get young plants established as they are more frost susceptible, but once established, the only maintenance will be cutting back the runners from where you do not want them to grow. A mature patch of plants will try to expand at a rate of about 1 foot (30 cm) per year. This is easy to maintain and keep in bounds.

Concerns:
None.
