- Description
-
The rosary pea is an evergreen vine in the bean family (Fabaceae) that is native to India and parts of tropical Asia. It was imported to Florida and is now listed as a noxious weed and is on the Federal Noxious Weed List. It is illegal to grow this poisonous plant.
This plant grows as a twining vine and can climb over trees and shrubs, invading both undisturbed and disturbed areas. The deep taproot makes it difficult to eradicate.
The shiny red and black seeds are very uniform in shape and have been used as a measure of weight and for jewelry. Birds will eat the fruits, spreading the seeds, and are unaffected by the poison. The pea-shaped flowers grow in clusters in the axils of the compound leaves.
Control of the plant is by hand pulling, aggressive tilling and chemical applications.
