Washingtonia filifera seed
The California fan palm is one of the most widely grown palms in subtropical climates. California fan palm can grow 60 ft tall with a crown spread of 15 ft. The large gray trunk is barrel shaped and ringed with old leaf scars that may reach over 3 ft in diameter. California fan palm can have up to thirty gray-green palmate (fan-shaped) leaves, each 3-6 ft across. They spread out to form a loose and open crown. The leaf stems of a mature palm are armed with long curved thorns. The leaflets are pendulous and swing freely in the wind. Cotton-like threads are on and between the leaflets and persist even when the palm is mature.
