Garden uses for Cordyline australis in NZ

Cordyline australis is a much-loved, NZ native tree that is widely used in NZ gardens. It is commonly grown as a specimen, added to a mixed planting, or used as a backdrop for smaller plants. It is an excellent complement to a modern or native garden, where it is often planted in clusters, with the added advantage of attracting native birds. It is the tidy form and foliage that make Cordyline australis an excellent choice for a NZ garden.

Why is the Cordyline australis common name Cabbage tree?

The common name "Cabbage tree" for Cordyline australis has a fascinating history, tied to how early European settlers and sailors perceived and utilized the plant. The central, unopened leaves of the Cordyline australis, particularly the young shoots, could be cooked and eaten. To early European settlers, this edible core resembled a cabbage, hence the name. It is also noted that the term "cabbage tree" was already in use by sailors for various palm trees in other parts of the world, where the terminal buds were also eaten. So, the term was already in use and was then applied to the Cordyline australis.

What is involved with transplanting Cordyline australis?

Transplanting Cordyline australis can be tricky, especially with mature plants, as they don't like root disturbance. Winter is generally the best time for transplanting, as this allows the plant to establish new roots before the heat of summer arrives. Cordyline australis can be sensitive to root disturbance, so minimising any damage or loss of roots during transplanting is essential. This means you’ll want to take as much soil with the plant as possible when digging one up. When replanting the tree, ensure the site is well-drained, as Cordylines are susceptible to root rot in waterlogged soil. However, be sure not to let the site dry out, as the tree will need to establish and grow more roots. NB: Older, larger Cordyline australis will be more difficult to transplant successfully, and the chances of success diminish the bigger the tree. You may want to consider purchasing a large-grade tree from a nursery, such as The Plant Company, which can be planted without issue.

What is the growth rate of Cordyline australis?

Cordyline australis will eventually reach 8 m tall and 3 m wide, but it can take 10-15 years to reach this height. If the tree is grown in favourable conditions, such as a well-drained site in full sun that is protected from wind, the growth rate will be faster than in less favourable conditions. As a general guide, the Cordyline australis growth rate is 50-70 cm of height gain per year.

What does Cordyline australis need to grow well?

Cordyline australis performs best when grown in full sun on a well-drained soil. The critical element is a well-drained soil, as the tree can succumb to root rot on wet soils. Wind protection is crucial during the early stages of growth to achieve good form, so consider staking the tree, which will help it establish quickly. Apply native tree fertiliser in spring across the soil surface to help grow a fantastic tree.

Cordyline australis care

Cordyline australis thrives in full sun to partial shade. It prefers well-drained soil, which is crucial to prevent root rot and tree death. It can tolerate a range of soil types, including sandy, loamy, and clay soils, as long as drainage is adequate. Once established, it is relatively drought-tolerant, but it will benefit from occasional deep watering during prolonged dry periods, especially when young. The recommended feeding regime is to scatter native tree fertiliser across the soil surface in spring. This will keep the tree fed for the next 12 months. Minimal pruning is required aside from removing dead or damaged leaves. The tree can, however, be cut back in summer if it becomes too large. Keep an eye out for pests like mealybugs, scale insects, and spider mites.

Does the Cordyline australis flower smell?

Cordyline australis flowers do have a scent, and their smell is quite noticeable. The flowers produce a strong, sweet fragrance that can be pretty pervasive, especially in the evening. Many describe it as a lily-like scent. However, scent perception is subjective. While many find it pleasant, some people report less favourable comparisons, saying it smells like cat urine or other unpleasant odours. Nevertheless, the strong scent is effective in attracting pollinators, particularly bees, which are drawn to the nectar-rich flowers.
