Coccothrinax argentata: Silverpalm1

Edward F. Gilman and Dennis G. Watson 2


This slow-growing, small, native Florida palm can reach 20 feet in height but is usually seen at 6 to 10 feet with a spread of 6 feet. The slender silverpalm has distinctive dark blue-green, drooping, delicate, deeply divided palmate leaves which have a beautiful silver color beneath, providing a bright glint in the landscape when the leaves sway in the wind. The 6-inch-wide trunk is either smooth and grey or is sometimes covered with woven, burlap-like fiber. The small, white flowers are borne in profusion on 2-foot-long stalks, hidden among the leaves during the summer. The small, round, purple fruits ripen in late summer and fall.

Use and Management

This palm is most suited for residential and commercial landscapes were the unusual blue foliage can be appreciated. It makes a nice accent in a shrub border, and can be massed together to create a dramatic colorful impact. Place it in a low-growing groundcover to provide an exclamation point in the landscape.

Growing in full sun or partial shade, silverpalm will tolerate any well-drained soil. The palm will grow straight up and provide a beautiful blue accent, even in areas receiving only two or three hours of sun. It is highly salt-tolerant and is especially useful for coastal locations and for soils with a high pH.

Propagation is by seed.
