Brahea brandegeei is a tall, slender, solitary-trunked, slow growing palm that eventually reaches 125 feet tall and is the tallest of the Braheas. At maturity, it has a large amount (40-70) of palmate (somewhat hand-shaped) green to silvery green leaves, with slender, thorned petioles (leaf stalks), in its crown. Dead leaves remain attached to the trunk, forming a petticoat, but eventually detach above their base. The trunk is naturally shaggy gray or brown from retained leaf bases. Fragrant, pale yellow flowers, clustered along short flower plumes which do not protrude beyond the leaves, appear in late winter. The fruit are spherical, less than one inch across, and brown when ripe. The roots are moderately aggressive.
