Cultivation

This species is easily grown from fresh seed, and is very popular in cultivation in Australia, both for private gardens and as a street and park tree. It is fast growing and will tolerate cooler climates outside the tropics where there are no frosts, and has been widely planted in many countries. It has become naturalised in Hawaii.
