Trachycarpus fortunei
Its texture is very rough, with the persistent leaf bases clasping the stem as layers of coarse dark grey-brown fibrous material.It tolerates cool, moist summers as well as cold winters, as it grows at much higher altitudes than other species, up to 2,400 m (7,874 ft) in the mountains of southern China.[7][3] Trachycarpus fortunei is cultivated as a trunking palm in gardens and parks throughout the world in warm temperate and subtropical climates.[3][10] Due to its widespread use as an ornamental plant, the palm has become naturalised in southern regions of Switzerland, and has become an invasive species of concern.[12][13][14] The cultivar group Trachycarpus fortunei 'Wagnerianus' is a small-leafed semi-dwarf variant of the species selected in cultivation in China and Japan.
