Trachycarpus fortunei (Chusan palm) is a slow-growing evergreen palm with an impressive head of divided fan-shaped leaves. Mature plants may produce large clusters of creamy yellow flowers in early summer. Not fully hardy. Height to 33ft (10m), spread to 10ft (3m) in warm sheltered conditions. Cultivar wagnerianus is a useful dwarf form with more compact fronds. Height 10ft (3m) or more.
Trachycarpus princeps one of the hardiest of the genus with a slight blue leaf colouration. Can be difficult to grow but worth the effort.
