Answer: Erythrina caffra is native to South Africa, so summer heat shouldn't bother it. In fact, once the tree is established, it will need little to no water in the summertime. Kaffirboom coral trees are briefly deciduous, losing their leaves in January. Big clusters of deep red-orange flowers develop on bare branches from January through March, then new leaves sprout. The tree will grow 25-40 feet tall with a 40-60 foot spread. To eliminate too-rapid growth, keep water to a minimum during the summer months. Prune after flowering to help maintain shape.
