Hesper Palm

Brahea

A genus of 12 species of Fan Palms that are closely related to the Washingtonias.
Most are very attractive and make great landscaping plants. They are entirely native to Mexico and adjacent parts of Central America.
The Hesper Palms require little maintenance other than the typical pruning off of old spent leaves though it is recommended to leave the leaf bases to protect the trunk.
If the old leaves are not removed.
All species are very heat and drought tolerant as well as being tolerant of salt.
Propagation is easily achieved from sowing the seeds which usually germinate in 2 months or less. They are very slow growing at first, increasing in rate once the trunk has formed.
