The Washington palm is a very elegant palm and one of the most resistant to cold but also very fast growing, it reaches 20 meters in its original habitat.
The stipe is wide at the base and thin and slender. The leaves are green in color and palmate and rounded in shape. The inflorescences are spectacular and can reach 4 meters in length. They bear numerous small whitish flowers. The Washingtonia robusta only flowers outdoors. The fruits are blackish in color when ripe.
Growing faster than Washingtonia filifera, Robusta thrives in all climates, from temperate to tropical. It is very resistant to frosts and drought. However, substantial watering will greatly accelerate its growth.
This palm tree is easy to care for. Simply remove or prune the dry leaves. Rain or a mist of water will kill the dust that always ends up accumulating on the leaves.
Indoors, place your palm tree in a very bright place but out of direct sunlight. Take your palm tree out during the summer period on the terrace or balcony. In winter, limit watering to a strict minimum.
The name Washingtonia was given in honor of the first American President George Washington.
