- Description
-
Cabbage Tree is a flowering, evergreen, single or multi-trunked tree in the asparagus family and one of the most recognized plants in its native New Zealand. The plant can reach a height of 30 to 60 feet in its native habitat at maturity. It can also be grown as an ornamental in a container and, in that environment, will slowly develop a cane-like trunk or trunks and reach a height of 15 feet. The small, fragrant flowers of the Cabbage Tree bloom in late spring. The leaves of the tree are sword-like with a 3 foot length and 3 inch width and cluster at the tips of the branches. The genus name comes from the Greek word kordyle meaning a club. The species name means southern.
Cabbage Tree tolerates a wide range of soils ranging from wet boggy conditions to dry ones. If grown outdoors, it does best in moist, fertile, organically rich, well-drained soils in full sun to part shade. When grown in containers outside on patios in summer, it can be brought in over the winter or grown indoors year-round as a houseplant. If grown in a container, keep soils consistently moist in summer but reduce moisture indoors in winter and site the plant in bright sunny spots in the home or greenhouse. Also note that container-grown plants rarely flower.
Cabbage Tree has a taproot that needs the root space of a large and deep container for best growth. Young plants consisting of a fountain of grass-like leaves with no trunk are often sold as houseplants. A tree grown outdoors will typically take 6 to 10 years before flowering.
Diseases, Insect Pests, and Other Plant Problems:
Mealybugs, scale and spider mites are possible, particularly on indoor plants. The plant is toxic for dogs and cats.
