Plant Profile – Cordyline australis
Cordyline australis varieties have been very popular with both landscapers and the home gardener in recent years. Cordylines give year round colour and great architectural foliage, providing any eye catching point of difference in the garden or the landscape. They are known for their attractive evergreen sword like leaves coming in a range of colours and variegations.
These Cordylines compliment other plants in the garden such as palms and other native and exotic plants. They can provide a tropical look and feel especially in the more temperate or cooler areas of Australia. Cordyline australis or New Zealand Cabbage Tree as they are more commonly known as is quite a tough plant. Recent droughts have really tested Cordylines in some regions and sure they are not as drought tolerant as Dianella or Lomandra but for garden areas where they are generally planted they have worked well. When the rain has eventually come again they often bounce back to former glory.
Most people are unaware that Cordyline australis can grow up to 8m tall but most of the newer varieties on the market will grow smaller to around 2-2.5m tall. A couple new varieties that are on the scene are Cordyline Sunrise and Cordyline Coral which do have a lot of appeal.
Sunrise is a very colourful selection which stands out with its vivid pink to maroon variegated foliage. Sunrise is far more heat tolerant than other pink types available. Its foliage stays cleaner through the summer and even in the colder temperatures it holds up very well. If you want eye catching colours and vivid colour than Sunrise is for you. Sunrise will grow up to 2m in height and it takes several years for it to develop a trunk of any size. It is a great feature or specimen plant.
Coral on the other hand has soft pastel pink and darker brownish green colour tones which provide the natural contrasts often required in a landscape. Often a more pastel colour is required to contrast with the greens of a landscape and you do not always want or need eye catching colours. Coral is perfect because it gives you the subtle foreground or background contrasts whether it is used as a feature or a mass planting. Coral is a hardy plant and is less likely to burn in the sun and discolour in the winter. If a more vivid colour is required to break things up, than Sunrise will do this better.
With both the Sunrise and the Coral they do respond very well to ground pruning, so if you desire a plant without the trunk simply cut them back to 15cm above the ground in spring or autumn. The plants will then start to reshoot from a lower point giving you more branching.
