Erythrina zeyheri is a wonderful plant for a small garden or town house, but very difficult to dig out as the rootstock becomes enormous. Select a site where it can expand without causing problems in your garden. The plants are not affected by the cold, as the above-ground parts die down for the winter period.  The plant will need excellent drainage if it is to thrive in areas with heavy winter rains (Mediterranean climates). You could try it in a large pot, where it would make a most unusual specimen plant.

This shrublet is only propagated from seeds that have been immersed in boiling water overnight and soaked. Once the seeds have been soaked they are ready for sowing. Sow the seeds in 5 mm diameter seedling trays or pans. Use a sifted loam and bark mixture. The seeds should be covered with the mixture not more than 1mm thick, otherwise the seeds will not germinate easily. The soil medium should be keep moist at all times, but do not over-water. Use a mist or fine spray for watering, otherwise the seeds will be washed out.

Spring (late August to September) is the best time to sow the seed, because the soil is warm and it is the growing season.
