This one can be shrubby or grow into a small tree, depending on how you prune it. The bright yellow flowers appear in clusters at the ends of the branches in mid-autumn and continue until frost. In frost-free areas they may continue to bloom throughout the winter.
Sulphur butterflies utilize this plant both for nectar and as a larval food source. In Florida this species is a caterpillar host for five of the nine native species of Sulphurs. The caterpillars that feed on the leaves will be mostly green, but those that feed on the flower buds will be yellow.
