Washingtonia filifera
California fan palm
a medium to large palm, with a robust trunk. The long leaf stalks have sharp teeth near the base, and the fan-shaped, grey-green blades up to 3m long are erect at first, then spreading and arching. Dead foliage remains on the plant, hanging down to clothe the whole trunk. Creamy-white, tubular flowers are produced in huge sprays up to 5m long, usually in summer
