Shagbark Hickory

Native to eastern North America across a broad range.

• Found from southeastern Canada (southern Quebec and Ontario) west to Minnesota, south to eastern Texas and northern Florida
• Most abundant in the Ohio River Valley and the Appalachian region
• Found at elevations from sea level to approximately 900 meters
• A component of rich, moist deciduous forests, often growing with oaks, maples, and tulip tree
• The species name "ovata" refers to the oval shape of the nut
• Hickory wood was so important to early American industry that the word "hickory" became synonymous with toughness and resilience ("hickory tough")
• Native Americans used hickory nuts as a major food source, pounding them into a nutritious butter or flour
• Andrew Jackson, the 7th US President, was nicknamed "Old Hickory" for his toughness — comparing him to the tree
• The genus Carya was named after the Greek word for walnut, karya

A large, stately deciduous tree with a narrow, oval crown and unmistakable bark.

Bark:
• The defining feature — gray bark that separates in long, curling, shaggy strips
• Strips curl outward at both ends, remaining attached in the middle
• Creates a dramatic, shaggy winter silhouette
• Bark texture becomes pronounced at 20 to 30 years of age

Leaves:
• Alternate, pinnately compound, 20 to 40 cm long with 5 (rarely 7) leaflets
• Terminal leaflet largest, 10 to 18 cm long
• Leaflets lanceolate, finely serrated, yellow-green above, paler beneath
• Turn rich golden-yellow in autumn — among the finest fall colors of any hickory

Flowers:
• Monoecious — male and female flowers on the same tree
• Male flowers in pendulous yellow-green catkins, 5 to 10 cm long
• Female flowers in small terminal spikes of 2 to 5
• Wind-pollinated in mid-spring

Fruit:
• Round to slightly pear-shaped nuts, 2.5 to 4 cm
• Enclosed in a thick, four-valved husk that splits to the base when ripe
• Shell is relatively thin for a hickory — easier to crack than most
• Kernel is sweet, rich, and considered the best-tasting of all hickory nuts

Form:
• 20 to 30 meters tall with trunk diameter 30 to 80 cm
• Crown narrow, oval, with ascending branches
• Straight central trunk

The Shagbark Hickory is an ecologically significant tree in eastern hardwood forests.

Habitat:
• Found in rich, moist, well-drained deciduous forests
• Prefers deep, fertile loams but tolerates drier upland sites
• Often found on lower slopes, in coves, and along stream terraces
• A long-lived component of mature oak-hickory forest communities

Ecological interactions:
• Nuts are a crucial fall and winter food for squirrels, chipmunks, wild turkeys, blue jays, and bears
• Hickory nuts have the highest fat content of any North American nut — critical for wildlife winter survival
• Shaggy bark provides habitat for insects, bats, and overwintering butterflies (including the endangered Indiana Bat)
• Host plant for Luna Moth and the spectacular Hickory Horned Devil (regal moth caterpillar)
• Deep roots bring nutrients up from subsoil layers, enriching surface soils

Growth:
• Slow to moderate growth rate of 20 to 40 cm per year
• Very long-lived — 200 to 350+ years
• Develops a deep taproot that makes it extremely wind-firm
• Sprouts vigorously from cut stumps

A slow-growing but rewarding tree for patient landscapers and nut enthusiasts.

Site selection:
• Full sun
• Deep, fertile, well-drained loamy soils
• Tolerates drier sites once established
• Allow ample space — deep taproot makes it difficult to move once planted
• Excellent for large landscapes, naturalized areas, and edible landscaping

Planting:
• Plant seedlings or grafted trees in spring
• Difficult to transplant due to deep taproot — plant small, container-grown trees
• Dig a deep planting hole

Care:
• Water during the first 2 to 3 years to establish the taproot
• Very drought-tolerant once established
• Minimal pruning needed
• Harvest nuts in autumn as husks begin to split
• Generally pest-free, though hickory bark beetles can be problematic
• Hardy in USDA zones 4 to 8

The Shagbark Hickory produces some of the finest wild nuts and toughest wood in North America.

Edible nuts:
• Sweet, rich, buttery kernels — considered the finest wild nut in eastern North America
• Commercially sold as a specialty wild food, commanding premium prices
• Used in baking (hickory nut cake, cookies, pie), candy, and as a table nut
• Native Americans pounded them into a nutritious butter and flour
• Hickory nut milk was a staple beverage for many Native American peoples

Timber:
• Wood is among the toughest, strongest, and most shock-resistant of all North American hardwoods
• Used for tool handles (axes, hammers, picks), wagon wheels, skis, and early aircraft propellers
• The preferred wood for smoking hams and bacon — hickory-smoked flavor is iconic
• Used for baseball bats, ladder rungs, and drumsticks

Ornamental:
• Spectacular shaggy bark provides outstanding winter interest
• Golden-yellow fall color
• A unique and distinguished specimen tree

Other:
• Wood used for smoking meats — the signature "hickory-smoked" flavor
• Bark used in traditional medicine for arthritis and rheumatism
