Coral trees (Erythrina lysistemon) have a colourful mass of red flowers. The flowers look even more spectacular on the bare branches of the deciduous trees. The dazzling flowers make it one of the best known and widely grown trees in South Africa.
The flowers produce abundant nectar that attracts many nectar-feeding birds and insects, which attract the insect-feeding birds as well. Birds such as barbets and woodpeckers nest in the trunks of dead trees, and swarms of bees often inhabit hollow trunks.
