The various species of Erythrina can all, as far as is known, be intercrossed to produce fertile hybrids.

Most Erythrina species are very easy to grow from cuttings, with even quite large branches striking well. In addition, they generally fix atmospheric nitrogen, have nutrient-rich leaves that make an excellent soil-enriching mulch, often have open crowns that do not overly restrict light, and are also often quite thorny and can provide impenetrable barriers to protect from unwelcome intrusions. Many species are therefore used as living fences to provide boundaries and livestock-proof hedges[

The greyish white wood sometimes has shades of red. The grain is usually straight; the texture coarse. The wood is light in weight; soft; not durable, being prone to fungal and wood-borer attacks, though it is moderately resistant to termites. It is easy to work, but planed surfaces may be woolly; it does not split when nailed, but the nail-holding capacity is poor. The wood is commonly used for making carvings, stools, drums, mortars, beehives, tool handles, brake blocks and floats for fishing nets, and sometimes also in house construction[
