Suriana maritima Bay Cedar

Edward F. Gilman, Ryan W. Klein, and Gail Hansen


Introduction

The bay cedar is endemic to south Florida, the Caribbean, Central America, and the Bahamas. It was commonly found growing in thickets, on sand dunes and rocky shores, often just back of the high tide line, but is now on the endangered plants list. This 5- to 20-foot-tall plant has a sturdy, branched trunk that has beautiful, dark brown, rough, flaky bark; the wood of this tree is very hard and heavy. Branches arch gracefully and hold the evergreen leaves on short, upturned twigs. The tiny, gray-green leaves are fleshy and minutely downy; the new leaves and twigs are particularly downy. Yellow, cup-shaped flowers may occur singly or in clusters that are inconspicuously set among the leaves. These small flowers occur consistently throughout the year. The seeds of the bay cedar are held in a small, brown, five-pointed calyx.

Use and Management

Bay cedar is not commonly used in the landscape but could function as a specimen or border plant in beach locations. It has been used as a hedge because it responds well to clipping. Left to grow on its own, bay cedar can be trained into a small tree for a specimen planting in the landscape or in a container. Planted in a row on 5- to 6-foot centers, it functions as a screen.

Bay cedar has a high tolerance for salt and wind and is ideal for coastal landscapes. It will grow well in well-drained, sandy soils without irrigation once established and needs to be placed in a mostly sunny location.

Bay cedar is currently propagated by seed.

Pest and Diseases
