The plant grows into a small, multi-trunked tree. It reaches 3 to 5 metres in height. The trunks are slender and upright. They branch at the base to create a bushy, multi-stemmed form. The overall shape is architectural. Leaves radiate from the tips of each stem like a fountain. Purple Cabbage Tree produces large, branched flower heads in summer.
