Washingtonia robusta - Skyduster, Mexican Cotton Palm - 5pcs seeds/packet
This is the slimmer of the two species of Washingtonia and considered to be slightly less cold tolerant, though it grows considerably taller than W. filifera. When young, the two species are not easy to tell apart, though it becomes increasingly evident as they mature. In some areas, W. robusta may be somewhat overused and is often the first choice of the street planner, influenced no doubt by its ready availability, fast growth, and consequent low price, but also by its many virtues as an avenue tree. Given the choice of the two species of Washingtonia, however, W. robusta should be chosen over W. filifera by those in areas of higher rainfall, as it is more tolerant of dampness and humidity than its cousin, and will do well in almost any climate between temperate and tropical.
