Brahea is a genus of palms in the Arecaceae family. They are commonly referred to as Hesper Palms and are endemic to Mexico and Central America. All Hesper Palms have large, fan-shaped leaves.


Read about Brahea in the Standard Cyclopedia of Horticulture 

Brahea (Tycho Brahe, the Danish astronomer). Palmaceae, tribe Corypheae. Medium-sized, usually spineless palms except on the leaf-stalks, with ringed trunks, the upper part of which is usually clothed with the persistent leaf-bases.

Leaves usually numerous, nearly round and somewhat peltate, the many lfts. plicate and deeply 2- parted, sometimes slightly spiny on the margin, more often filamentous; petioles flattened, dentate or rarely spiny along the margins, very fibrous at the sheathing base: spathes usually linear, firm, almost woody, frequently perfectly glabrous; spadix much branched, sometimes twice or thrice paniculate and bearing among the dense white wool 1 or many sessile fls. in each cluster; fls. hermaphrodite, sometimes with inconspicuous bracts, 3 nearly round sepals, 3 valvate petals and 6 stamens: fr. small, ovoid, sometimes pubescent. Beccari admits only 4 species, all Mexican except B. salvadorensis. From its nearest horticultural relative, Sabal, Brahea is distinguished by the purely technical character of having 3 free carpels.

In a moderately warm house, the cultivated braheas will thrive very well. A mixture of sand, rich loam and well-rotted horse- or cow-manure is best. They require plenty of water. They are not very common in the trade but two species are grown outdoors in southern California. Propagation is by seeds, which are rare.

B. edulis, Wendl., sometimes offered in Amer., is Erythea edulis, Wats. — B. filamentosa, Hort. Washingtonia filifera. Wendl. — B. filifera, Hort.-W. fiiifera. — B. glauca, Hort. - Erythea armata, Wats. — B. robusta, Hort.-Washingtonia. — B, Roezlii, Erythea armata, Wats.

Hardy to 18F/-8C. Slow grower. Trunk is flexible and slim, gray and smooth, 18 in. (45cm) in diameter. Leaves usually fall off, but sometimes are persistent. Bluish/Silver tint to the leaves, can look nearly white, with 25-30 leaves on a healthy tree. Leaves are divided into 40-60 leaflets. Cream colored flowers are very visible and hang low in large clusters, much longer than leaves. Can withstand wind and heat well. Seeds will sprout for a few years after production, but are always sporadic, taking 1-12 months to sprout. The brown round fruit comes in at 0.8 in. (2cm) and is edible.
