Peltophorum africanum (African wattle)

Peltophorum africanum is one of our most wonderful flowering indigenous trees. With it’s dense, spreading, rounded crown and showy golden yellow flowers the African wattle is a must for dry or windy situations. The spectacular flowers of this hardy tree provide a high yield of pollen and nectar which is perfect for bee keeping. One of the common names for this charming tree, ‘Weeping wattle’, refers to the moisture that drips from the branches before the first rains. This is caused by nymphs or small frog hoppers called spittle bugs that suck sap from the trees which they excrete as almost pure water. Butterflies, bees and birds are all attracted to this lovely tree which provides them with food and shelter in an urban setting.
