Cuttings root easily. Erythrina is a genus containing some 100 trees and shrubs, most with spiny trunks and branches and a number that produce strikingly beautiful flowers. The dwarf coral tree is an ideal tree or shrub for the small garden, especially for people who love the scarlet flowers of the common coral tree (Erythrina lysistemon) but don't have the space for a large tree. Its small dimensions make it ideally suited to high density housing complexes where garden space is limited. It produces an impressive display of scarlet red flowers en-masse, which are a favorite with many different birds who enjoy the nectar. It likes full sun and well-drained soil and bloom best after a period of drought. Quite large cuttings root easily.
