Chinese windmill palm (Trachycarpus fortunei) — identification, habitat & look-alikes

Chinese windmill palm is one of the most palms commonly grown in U.S. landscapes. Its trunk is covered in brown fibers, and its rounded crown has large, fan-shaped leaves. Chinese windmill palm is also called windmill palm.

Appearance

Appearance: A single fibrous trunk supports a rounded crown of fan leaves. In cultivation it is often about 10 ft (3 m) tall, while wild plants can reach 20–40 ft (6–12 m).
Leaves: Each roughly 3 ft (0.9 m) fan is divided into narrow segments with slightly drooping tips. Old leaf sheaths leave long brown fibers around the trunk.
Flowers: Drooping, branched flower clusters emerge among the leaves. Male flowers are yellowish, while female flowers are greener.
Fruit: Female plants produce small, lumpy s that mature dark blue to nearly black, with one seed in each fruit.

Look-alikes

Mexican fan palmWashingtonia robusta

Chinese windmill palm has a shaggy brown-fibered trunk and usually stays under 40 ft (12 m). Mexican fan palm develops a much taller, slender gray trunk and has conspicuous teeth along the leaf stalks.

Why they get mixed upBoth are single-trunk landscape palms with large fan-shaped leaves.

Where it lives

Typical habitats: protected gardens
patios
partly shaded borders
Range: It is native to south-central China and northern Myanmar and is cultivated across temperate parts of the United States. It is not native to North America.
Preferred conditions: It grows in full sun to partial shade in moist, well-drained soil. Shelter from strong wind keeps the fan leaves from tearing.

Life cycle

Reproduction: Separate pollen-producing and fruiting plants are usually needed for seed. Gardeners propagate the species from seed.

Growing it

Care: It grows in 7a–11b, and established palms can tolerate about 10°F (-12°C) or slightly lower. Young plants still benefit from winter shelter.

Name and classification

About the name: Trachycarpus wagnerianus is an older name for the form sold as ‘Wagnerianus’.
Varieties and forms: Plants sold as ‘Wagnerianus’ have smaller, stiffer leaves and are more resistant to wind damage. They are included here as a cultivated form of Chinese windmill palm.

Conservation

IUCN Red List: LCLeast ConcernLow risk of extinction
Status: Its global population trend is stable, with no major current threats identified.

Culture and stories

Culture and stories: The fibrous trunk covering has long been used in China for rope, brooms, mats, and cloth.
The species name honors Robert Fortune, the 19th-century plant collector who introduced the palm to European horticulture.
