Answer: Erythrina caffra, or coral tree, really will grow in full sunshine. However, since yours are in containers they can be more sensitive to the heat, and I suspect they were grown and stored in a shaded nursery area. If you gradually acclimate yours to full sunshine, they should be fine. You can do this while they are still in the nursery pots or you can plant them and provide temporary shade until they acclimate. Just start by giving them an hour or two of morning sunshine, increasing the amount of sun they receive every few days. In about 2 weeks they should be able to tolerate full sunshine all day long. Try to protect the roots from overheating by blocking direct sunshine to the containers. Hope this answers your question.
