Description

General aspect and origins - Washingtonia robusta, also known as the Mexican fan palm, is native to northern Mexico, and can reach up to 75 ft (25 m) tall, with a trunk that can be 12-16 in (30-40 cm) wide. The Mexican fan palm has a less massive aspect than its close relative, Washingtonia filifera, the Californian fan palm.
Leaves - The Mexican fan palm has an evergreen foliage. Leaves are about 4.5 ft (1.5 m) long. Beware of leaf stems that have sharp spines. As the leaves die, they often remain attached to the trunk and give these palms their specific aspect, which explains the common name "fan palms".
Flowers - This palm has showy yellow-cream inflorescences can be up to 13 ft (4 m) long and that bear numerous small white flowers.
Fruits - Fruits are black when ripe.

Culture

Washingtonia robusta is a little less frost tolerant than its close relative Washingtonia filifera, but still can withstand negative temperatures down to 18°F-22°F (-6°C to -8°C).
Soil - This palm prefers a well-drained ground.

Propagation

This palm can be propagated by seeds, which are relatively easy to germinate, provided they are fresh enough. This palm is relatively fast growing.
