Trachycarpus

Trachycarpus, is a genus of ten species of palms native to Asia, from the Himalaya east to eastern China. They are fan palms (subfamily Coryphoideae), with the leaves with a bare petiole terminating in a rounded fan of numerous leaflets. The leaf bases produce persistent fibres that often give the trunk a characteristic hairy appearance. All species are dioecious, with male and female flowers produced on separate plants although female plants will sometimes produce male flowers, allowing occasional self-pollination.

Cities as far north as London, Dublin, Paris, Seattle and Vancouver have long term cultivated palms in several areas. The dwarf form, known as T. wagnerianus, is unknown in the wild, and is now considered synonymous with T. fortunei or treated as a cultivar of that species. It resembles T. fortunei closely, differing only in its smaller and stiffer leaves. Hybrids between the two are intermediate in size and fully fertile.
