Trachycarpus fortunei seed
common name: Windmill Palm,Chusan Palm
Trachycarpus fortunei, the Chinese Windmill Palm is one of the most cold hardy palms available. It is beautifully compact and grows to heights of 20-40ft. This palm has a rather slender single stem that is 8-10 inch in diameter and is typically a bit narrower at the base than at the top. Trunks are usually covered with a loose mat of coarse gray or brown fiber. In older individuals the fiber sloughs away to reveal a smooth ringed surface. Chusan palm, as it is also commonly called, has light to dark green palmate leaves that are lighter, almost silvery (glaucous), on the underside. They are held on thin 3ft flattened stems that are finely toothed along both edges. Leaves are circular, about 3 ft in diameter and segmented about halfway. Leaves are arranged into a symmetrical crown that is about 8-10ft wide. Specimens grown in full sun and/or under poor conditions may have much smaller, more compact crowns.
