The Washingtonia Filifera is one of the tallest and most imposing cold hardy palms. This palm with webbed leaves is renowned for its rapid growth.
It has an imposing and slender stipe. The leaves measure up to 1.80 meters in length. The inflorescences are several meters long and carry very many small creamy white hermaphrodite flowers. It therefore only takes one subject to produce a fruiting body. The fruits are dark purple in color and measure about 1cm in diameter.
Well watered it grows quickly and resists drought very well. California palm needs well-draining soil. It will thrive in well-aerated but still cool soils. Conversely, it does not like excessive soil moisture in winter.
It can endure quite severe frosts (down to -28°C for short periods) with little damage.
