Shrub with erect habit and orange flowers — Brenda Herring

Description

A woody shrub to 4-5 m high. The bark is gray to reddish brown in color. The leaves are alternate, compound, and are 12-18 cm long. The flowers are red to orange-red and the fruit are conspicuously 4-winged. The seed pods are 7-10 cm long.

Habitat

Found in most of Florida, occurs in wetlands and brackish marshes. Tidal marshes and moist, disturbed sites.

Comments

Produces abundant seeds and is an aggressive wetland invader. Seeds may be spread great distances through water. Survives frost. Escaped from cultivation.

Control Methods

Manual: Cut larger plants and treat stumps. Pull young plants by hand or with a weed wrench. Mowing will help but is often not feasible due to wet soil conditions where this species prefers. Mechanical control prior to seed set will be helpful in controlling future infestations, but this must be practiced over a several year period as dormant seeds will continue to germinate. (IFAS)
Chemical: Glyphosate 41.0% L/2,4-D
Biological: NA
