In wintertime gardeners think a lot about what plants they’ll need to cover when cold weather strikes. One plant that doesn’t need protection is windmill palm.

Windmill palm (Trachycarpus fortunei) is not native to Florida but is considered Florida-Friendly. We love this palm because it is one of the most cold hardy available. It grows as far north as Canada and Scotland, but it’s also a versatile and attractive choice for North and Central Florida gardens.

Characteristics

Sometimes called Chusan palm, windmill palm is considered hardy in zones 8A–11, but it grows north of these regions as well and can handle temperatures as low as 10 degrees Fahrenheit.

Trachycarpus fortunei has fan-shaped fronds that are about 1.5 to 3 feet wide. The trunk is narrow, straight, slightly spiny, and looks like it’s been wrapped with burlap. In the summer and fall, clusters of yellow or white flowers appear. Small, blue fruits follow but do not attract wildlife.

Windmill palm’s compact shape makes it well suited for small yards or tight spaces like courtyards. The fruits and flowers do not present a litter problem making it a good choice for paved areas. Mature palms rarely grow above 25 feet high and their spread is only 6-10 feet. Windmill palms grow slowly, so small specimens will remain small for a number of years.

Planting and Care

This Florida-Friendly plant will grow best in partial shade and fertile soil. You can plant windmill palms in full sun but they may require irrigation during dry spells. Once established, they’re relatively drought tolerant. Windmill palms also do well in coastal neighborhoods, being moderately wind and salt tolerant as well.

Windmill palms are low maintenance. You can remove the dried fronds, but you certainly don’t need to. Occasional fertilizing can help prevent nutrient deficiencies. If you do fertilize, choose a slow release palm fertilizer (8-2-12).

Like many palms, Trachycarpus fortunei is vulnerable to root rot, lethal yellowing disease, and leaf spots. This palm is also susceptible to lethal bronzing disease, but the most common pests are scales and aphids.
