It commonly ranges in height from 4 to 10 feet and often occurs in coastal conditions and near wetlands.

Necklacepod is a nectar plant for bees, butterflies, and in parts of the Americas hummingbirds as well.

It is suggested for use by native plant enthusiasts in Florida as a good landscape plant for xeriscaping[5] but it only naturally occurs in coastal counties in the central and southern part of the state,[4] while closely related varieties occur in Texas, and the Caribbean.

[6] The variety of Necklacepod growing in Australia is considered an endangered species in some areas due to the clearing of coastal habitat and displacement by invasive species.

It has been used to make fish poisons, insect and spider repellents etc., esp in Africa.
