Washingtonia Filifera
Also called the Californian Washingtonia, this is a tree species from the Aceraceae family. Together with the Phoenix canariensis, Phoenix dactylifera and Chamaerops humilis, it is one of the main species of palm trees used in gardening in Mediterranean climates. Its main characteristics that differentiate it from the Phoenix genus is that its leaves are palmate (its leaflets all come out radially from the same point in the edge of the petiole instead of appearing along the main shaft like a feather) and the trunk is a lot thinner and taller (more than 15 m).
The trunk has small marks of rough fissures or it is partially covered by bits of leaves, its base is wide. Its fruit is elongated or oval in shape, blackish and 0.6 cm in diameter.
The ideal conditions for its growth are the hot summers but in winter it can cope with the cold quite well, including short periods of frost and freezing at 10 degrees below zero.
Resistance to cold: -10º
