Erythrina herbacea, Coralbean

Coralbean (Erythrina herbacea) gets a common name from its coral-colored seeds. It is also known as Cardinal spear, which refers to its red tubular flowers. It is a semi-deciduous to evergreen woody shrub found in coastal hammocks, sandhills, flatwoods, mesic and upland woods, and pine rocklands throughout Florida. Its striking scarlet flowers attract hummingbirds, bumble bees and butterflies.

Coralbean’s flowers are born in long (4–6+ inches) terminal racemes. Individual flowers may be as long as 3 inches. Leaves are compound and composed of three light green, deltoid-shaped leaflets, each with tiny prickles along the underside of its margin. The stem and irregular branches are also armed with short curved spines. Bark is light gray to whitish and may be rough or smooth. Fruits are large, light drooping pods that turn nearly black and split open when mature. Seeds are shiny and bright red with a black spot or stripe.
