Shellbark Hickory

Shellbark Hickory (Carya laciniosa)

The King Nut of the Forest

If there is one nut tree that earns true royalty status, it’s the Shellbark Hickory. Canadian botanist and author Diana Beresford-Kroeger has referred to hickories as the “King Nut” of North American trees and Shellbark sits at the very top of that crown.

This is the hickory with the largest nuts of the entire genus, wrapped in thick, rugged shells and packed with rich, sweet kernels that rival pecans for flavour. Historically prized by Indigenous peoples and early settlers, Shellbark Hickory is a once-in-a-generation tree that rewards patience with decades — even centuries of nut production.

Planted today, this is a tree for your children, your land, and your legacy.

Growing Information (Canada-Friendly)

Botanical name: Carya laciniosa
Common name: Shellbark Hickory
Plant type: Deciduous nut tree

Canadian Hardiness Zones:

• Zone 5–7 (Zone 4b possible in sheltered sites with good soil)

Mature Height:

• 60–80 ft (18–24 m)

Mature Spread:

• 40–50 ft

Recommended Spacing:

• 40–50 ft between trees

• Best suited to orchards, fields, or large food-forest systems

Growth Rate:

• Slow to moderate (especially in early years)

Sun:

• Full sun (best nut production)

Nut Production:

• Typically begins 10–15 years from seed

• Heavy crops once mature, with excellent consistency

Pollination:

• Wind-pollinated

• Planting multiple hickories improves yields

A True Legacy Tree

Shellbark Hickory isn’t a “quick return” tree it’s a forever tree. This is the kind of planting that defines land stewardship: deep roots, towering form, and food production that can last longer than any orchard crop.

If you’re building a serious food forest, restoring land, or planting for future generations, Shellbark Hickory earns its place proudly as the King Nut.
