General Description

Bearing bold, fan-shaped fronds atop a solitary trunk, this small, slow-growing palm from Hispaniola makes a great subject for tropical and subtropical gardens.

Thirty to forty large, bright green fronds are borne atop the trunk on long, ascending or drooping stems ("petioles"), forming a rounded crown. The fronds are divided into more than 100 stiff blade-like segments that radiate like the spokes of an umbrella. The petioles have tufts of white hairs, and are edged with hooked tooth-like spines. A picturesque "skirt" of drooping dead leaves often fringes the base of the crown. Plants are initially stemless, developing a trunk after a decade or more. Trunks of young plants bristle with the protruding, wedge-shaped petiole bases of fallen leaves, in the manner of a pineapple fruit. The petiole bases eventually drop to reveal the trunk, which is light to dark gray and ringed with grooved petiole scars. In spring or summer, dense clusters of small creamy flowers arch just beyond the leaves in branching inflorescences. The flowers are perfect, containing both mail and female parts. Small spherical fruits follow the flowers, ripening black in late summer or fall. Birds and bats eat the fruits.

Grow this palm in full sun to light shade in well-drained soil. It will tolerate drought and a touch of frost. It grows most vigorously if watered occasionally in summer. Use it as an individual specimen, in formal groupings, or in large containers.
