Zanthoxylum fagara Wild Lime1

Edward F. Gilman2

Introduction

Wild lime is a small tree native to south Florida and the Caribbean Basin (Fig. 1). It grows as an understory tree in the coastal upland plant communities on the lee side of the dunes in south Florida. Compound leaves have distinct wings along the leaf rachis and smell of lime when crushed. Most specimens in the woods have several stems emerging close to the ground. Specimens at nurseries can be grown with one or several trunks. Stems have sharp spines that can cause severe pain when they contact flesh.

Use and Management

Although tolerance to shade allows wild lime to germinate and grow successfully as an understory tree, it adapts well to the full sun. Plants grown in the full sun are full, nearly symmetrical and make nice multi-trunked small patio trees. They can also be planted in a container or other area with limited soil space due to the small size of the mature plant.

Pests and Diseases

There are no serious pests or diseases that limit growth of this native tree.
