Leucaena leucocephala, White Leadtree

Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop

In Florida, white leadtree is a prohibited species and therefore is not used in commercial applications in the state. However, in its native range it is used as a source of charcoal, fuel, and lumber. It has also been planted as a windbreak for crops such as coffee and cocoa, and some ranchers use the tree as a source of both shade and forage for cattle, with the pods being an excellent source of protein.

Cat's-Claw Vine, Dolichandra unguis-cati—A Showy but Invasive Plant in Florida

Niels Proctor and Jason Smith

Cat’s-claw vine is a neotropical, climbing perennial that produces large and showy yellow flowers in the springtime. It is valued as an ornamental, particularly in dry areas, because it needs little water or care and can climb almost anything, covering fences and other structures with an attractive carpet of leaves and flowers. Unfortunately, the aggressive nature of the vine has made it a major weed in China, Australia, South Africa, and parts of the southeastern United States. This 6-page fact sheet provides guidance on identification, control, and similar native vines for home landscapes.
