Known 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[

Cultivation Details

Erythrina zeyheri is found from the tropical regions of Zimbabwe to the warm temperate zone of eastern S. Africa. It experiences frosts in at least part of its range and should be able to be grown in warm temperate regions, especially if given the protection of being grown against the sunny side of a wall, and the stem bases are protected with a thick mulch of organic matter such as leaf litter or sawdust and then covered with bracken[

Propagation

Seed - germinates in 5 - 15 days[299.
Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
