Survives zone 7 through 9
Harvest calendar
Ripens: Seed ripens in October, in the autumn of the SECOND year after flowering
Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.
The seed, sold in China as xiangfei or 'fei nuts', is roasted and eaten as a delicacy with a rich, nutty flavor, and its oil is pressed separately for cooking — a genuine, centuries-old commercial nut crop rather than a foraging curiosity. Some individual cultivated trees in China have been harvested for over 1,000 years, among the longest-lived nut trees anywhere. Like the rest of the genus, the seed takes two full years to mature after pollination, so a bearing tree carries two overlapping generations of developing seed. Grafted cultivars fruit in 5–8 years; seed-grown trees can take 15–20 years or more.

- Seed
- Ripens
- Seed ripens in October, in the autumn of the SECOND year after flowering
- Mature size
- Large, slow-growing tree, typically 15–25 m tall (exceptional wild trees to 39 m)
- Light
- Full sun to part shade
- Soil pH
- Mildly acid to mildly alkaline; tolerates a wide range of soil textures
- Environment
- Warm to cool temperate; mixed mesophytic forest, often streamside
- Native range
- Central and eastern China — Anhui, Fujian, Guizhou, Hunan, Jiangsu, Jiangxi and Zhejiang provinces — angiosperm-dominated forest at 200–1,400 m, typically in riparian sites.
- Status
- Both wild and cultivated
- Growth speed
- Slow
- Spacing
- 600 cm (236 in) apart — about 36 m² (388 sq ft) per plant
- Leaf shape
- Stiff, glossy dark green needles in two flat ranks, sharply pointed
- Fruit description
- An olive-like, single-seeded drupe with a thin fleshy outer covering that is peeled away before the hard-shelled seed inside is roasted
- Propagation
- Fresh seed needing 18 months or more of cold stratification to germinate; commercial trees are usually grafted onto seedling rootstock to reach bearing age far sooner
- Pollination
- Wind-pollinated; dioecious — needs a male and female plant to set seed

Growing guide
Growing tips. Grown as a real orchard crop in parts of China on grafted, named cultivars; outside that tradition it is planted mainly as a slow, long-lived ornamental. Tolerates a range of soils and light levels but is slow at every stage, from germination to first seed.
