I know it as African wisteria tree. It is slow growing and likely to be small for a very long time, probably not getting more than 6ft tall in a central Florida garden. But it does bloom at about 2-4 years old and less than a foot tall. My garden is zone b and it has been happy outdoors here. It can take a light frost, but its size makes it easily protected. And it is certainly something every garden does not have. If you are into bonsai, this is an excellent choice. DR

A beautiful Wisteria like blooming south african tree. looses its leaves for a short while and then get coverd by flowers. Tends to form various trunks, but can be pruned to grow on one. possibly goog container plant. non-invasive root system.
