Washingtonia robusta (Mexican Fan Palm)

Washingtonia robusta (Mexican Fan Palm)

Washingtonia robusta, commonly known as the Mexican Fan Palm, is a tall, fast-growing palm valued for its slender trunk, fan-shaped fronds, and strong architectural presence. It is widely used in avenue planting, resort landscapes, and feature planting where height and a tropical effect are desired.

The palm produces a tall, smooth grey trunk topped with a crown of large fan-shaped green fronds. Older fronds may form a skirt beneath the canopy if left untrimmed. Mature palms also produce long clusters of small cream flowers followed by dark fruit.
