How to manage it
Outstanding subtropical performer. Grows straight up for timber and windbreak, with light canopy and showy winter flowers.
Watch out for
Can suffer dieback during severe frost; requires winter protection in colder inland microclimates. Not a fast chop-and-drop biomass producer despite vigorous regrowth.
