nutmeg hickory

Survives zone 6 through 9

Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Nutmeg hickory nuts are genuinely sweet-tasting, but the shell is so thick relative to the small kernel that most nuts are left to rot where they fall, since neither people nor wildlife find them worth the effort of cracking. The species gets its common name from the nut's appearance — reddish-brown with silvery stripes, resembling the spice nutmeg — and its leaves have a striking silvery-scaled underside that flashes in the wind, considered by some foresters the most ornamentally attractive hickory foliage.

Native range

Southeastern United States (from North and South Carolina west to Oklahoma and Texas, south to Alabama, Georgia, Louisiana and Mississippi) and northeastern Mexico, growing on river banks, in swamps and on rich moist soils, sometimes on higher ground, often over limestone.

Status

Wild

Years to fruit

6–10 yrs

Growth speed

Slow-growing, capable of reaching around 30 m in the wild.

Spacing

1200 cm (472 in) apart — about 144 m² (1550 sq ft) per plant

Leaf shape

Pinnately compound, with 5–9 (usually 7) ovate to elliptic leaflets; the underside is densely covered in silvery-white to bronze peltate scales that give the foliage a distinctive metallic sheen, especially in spring.

Root system

Deep taproot typical of the genus, making early, permanent placement important for successful establishment.

Fruit description

A small, rounded nut, only about 2.5 cm long, reddish-brown with silvery stripes and speckles, inside a thin husk with four ridges; the kernel is sweet but the shell is very thick relative to the nut's small size, making extraction impractical for most foragers.

Propagation

Propagated from seed, which requires cold stratification and is best sown in a cold frame as soon as ripe, one or two seeds per deep pot to accommodate the taproot. Seedlings should be moved to deep containers early and set in their permanent position, preferably in their first summer, with winter protection while young.

Pollination

DICHOGAMOUS — needs Type I + Type II cultivars (pecan); hickories benefit from a 2nd tree
