Washingtonia Robusta 10L/40L
Washingtonia robusta (Mexican Fan Palm or Mexican Washingtonia) is a palm native to northwestern Mexico. It grows to 25 m tall, rarely up to 30 m. The leaves have a petiole up to 1 m long, and a palmate fan of leaflets up to 1 m long. The inflorescence is up to 3 m long, with numerous small pale orange-pink flowers. The fruit is a spherical, blue-black drupe, 6-8 mm diameter; it is edible, though thin-fleshed.
Like the closely related Washingtonia filifera (California Fan Palm), it is grown as an ornamental tree. Although very similar, the Mexican Washingtonia has a narrower trunk (which is typically somewhat wider at the base), and grows slightly faster and taller; it is also somewhat less cold hardy than the California Washingtonia, hardy to about −-10 °C. Unlike the Washingtonia filifera, which has been cultivated as far north as Oklahoma and Southwestern Utah, the Mexican fan palm can be grown mainly around areas of the southwestern United States, such as California and the extreme south coast of Oregon(up to Gold Beach), Arizona, southern Nevada, and southern New Mexico. It may also be seen along the Gulf Coast from Texas and Louisiana to Florida, though specimens in that region will not be as tall as those along the West Coast due to a more common occurrence of deep freezes and also uprooting caused by tropical storms and hurricanes.
