Not all palms love water! This one is actually drought-tolerant and can live quite happily on little or no water once it’s established, though it’ll grow more slowly and may not look as lush. To keep your palm looking its best, be sure to water it consistently and deeply while it’s getting established, then after a few years give it a good deep soaking every couple of weeks. It will also be happy to have more water, provided the soil drainage is adequate.

Growing Notes

Leaves will be green when young, and get more and more silver as this palm matures. As this palm is new to cultivation, the height, width, and hardiness given here are our best guess at what this palm may mature into given how it grows in nature.
This solitary palm will grow only one trunk during its lifetime. Fan palms have leaflets spreading from the tip of the petiole, giving the crown of the palm a rounded full look. They tend to rustle in the breeze, adding a soothing note to the garden.
This palm holds its leaves for a long time, creating a beard or skirt on the trunk. If you want, you can always prune off the beard for a cleaner look.
Palms are generally heavy feeders, so if you want them growing quickly and looking their best, they should be fertilized at least three times a year. Fertilizing at spring equinox, summer solstice and fall equinox will allow for a winter rest. Be sure to feed your palm with a fertilizer that contains micronutrients, especially if you see yellowing leaves or yellow spots on the leaves.

Special Interest

We are thrilled to be growing this rare palm. This palm is undescribed in nature and very rare in cultivation. It looks similar to the other silver brahea -- armata and clara -- but, unusually for the genus, the petioles are totally unarmed (have no thorns).
