Te Ao Māori
This cultivar was selected for its rich purple-bronze foliage. It is a favourite for adding contrast and drama to garden plantings. The colour is most intense in full sun. It has no traditional Māori significance, as it is a modern cultivar. It represents the adaptation of a common native tree for ornamental use. Bringing the dramatic form of the cabbage tree into garden landscapes in a new colour.
It is not green. It is purple-bronze. A striking, large Cordyline with broad, sword-like leaves. A cabbage tree that breaks the rule. The leaves are long and narrow, up to 60 centimetres in length. They have a smooth, leathery texture. The purple-bronze colour is most intense in full sun, where the leaves take on a rich, metallic sheen. In shade, the colour may fade to a greenish-bronze. A plant that changes colour with the light. 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. The flowers are small, white, and fragrant. They attract bees and other insects. The flowers are followed by small, white berries that persist into winter. The plant is extremely hardy. It tolerates drought, wind, salt spray and frost.
