Erythrina herbacea (Coralbean)

Cardinal Spear, Coralbean, Cherokee Bean, Red Cardinal, Erythrina arborea


Thriving on neglect, Erythrina herbacea (Coralbean) is a multistemmed thorny deciduous shrub or small tree noted for its brilliant red tubular flowers borne in upright spikes, up to 2 ft. long (60 cm). Blooming in several waves between spring and fall, the showy blossoms resemble crescent moons and are particularly attractive to hummingbirds. They are followed by persistent hanging pods which burst open to reveal beautiful, bright red seeds, adding further interest long after flowering. Scattered along the stems, the alternatively arranged, trifoliate leaves feature long petioles and arrowhead-shaped leaflets. Dull green in color, they have prickles on the midribs and on the undersides. Coralbean is deciduous but retains its foliage late into the season. Evergreen in the tropics, this unusual tropical plant is killed to the ground in winter in places where freezing weather occurs. However, it will regrow in the spring. Coralbean is an excellent ornamental flowering shrub or tree, often used to give a woodland planting a naturalistic effect. It is also excellent as an accent or specimen plant.

  • Grows up to 6-12 ft. tall (180-360 cm) and 3-6 ft. wide (90-180 cm).
  • Easily grown in loamy or sandy, acidic to slightly alkaline, well-drained soils in full sun to light shade. Water deeply but infrequently in summer. Fertilize once during the growing period. Highly drought tolerant and moderately salt tolerant.
  • Protect from frost and stop watering during dormancy (after the leaves dropped).
  • Great as a specimen plant in Mediterranean gardens, informal gardens and native plant gardens.
  • No serious pest or disease issues.
  • Prune regularly to control size and encourage new growth from the base.
  • Propagate from scarified seed, semi-hardwood cuttings and root division.
  • Seeds are poisonous to humans and children if eaten. In Mexico, the toxic seeds have been used for poisoning rats and fish.
  • Native to Mexico and the southern Unites States.
