Safety & Hazards

All Erythrina species contain greater or lesser amounts of toxic alkaloids - these can be found in all parts of the plant but are usually most concentrated in the seeds. Concentrations vary from species to species, in some it is low enough that the plant is safely used as a food. In many, the alkaloids are utilized for their medicinal effects. We have no specific information on the concentration of the alkaloids in this species, but care should be exercised in any use of the plant that involves ingestion. These alkaloids have a curare-like action (obtained from Strychnos species) and can cause paralysis and even death by respiratory failure[1, PFAF].

Cultivation Details

HabitDeciduous Shrub
Growth—

A plant of the lowland tropics. Succeeds in a moderately fertile, well-drained soil[2]. Plants commence flowering when 3 - 4 years old[2]. All species in this genus are believed to be self-compatible. Their flowers are adapted to pollination by birds, though various insects can also cause fertilization. The various species of Erythrina can all, as far as is known, be intercrossed to produce fertile hybrids. Those species most closely related to each other cross fairly readily, but even species that are quite distant can hybridize[3, 4]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[5].

Propagation

Fresh seeds, and those harvested within 3 - 6 months of maturity, can be sown without any special treatment. Germination rates are generally high and are often 100%. Seeds over 6 months old may take between 12 - 18 months to germinate due to their hard seed coat which becomes tougher with age. Soaking them in hot water, or abrading their seedcoat, can reduce this time considerably. They may be added to water which has just fallen below boiling point and left in the water as it cools for a minimum of one hour, but up to 12 hours for seed 3 years or more old, and then sown in the usual way. Alternatively, file the seeds with a slender triangular file. A groove can be made through the sides of the seed coat with care so as to avoid damaging the cotyledons or embryo, which usually results in the death of the seeds from fungal attack or in malformed and weakened seedlings[6]. Seeds of most species produce strong seedlings from healthy seeds in almost any well-drained soil, with a minimum of trouble from damping-off disease[6]. Cuttings of half-ripe wood[2]. Heeled cuttings of young growth[2]. Cite as: Tropical Plants Database, Ken Fern. tropical.theferns.info. 2026-02-20. <tropical.theferns.info/viewtropical.php?id=Erythrina+corallodendron>
