Cordyline, also known as ti plants, cabbage trees, or Hawaiian good luck plants, are a group of evergreen, tropical trees and shrubs native to Australia, Southeast Asia, and the Pacific Islands. They are known for their colourful, elongated leaves and their ability to thrive in a wide range of conditions. The most widely grown species is Cordyline australis, which is native to New Zealand and can be grown from seed. While it typically takes years to develop sizeable plants, some varieties of Cordyline australis grow slower than others. For example, green-leaved forms are the largest and fastest-growing, reaching around 5 meters high, while coloured and variegated varieties are less vigorous and rarely grow larger than 2.5-3 meters high. Additionally, certain cultivars like Cordyline Raspberry Fountain have a slow growth rate, taking several years to reach their full size.
| Characteristics | Values |
|---|---|
| Growth rate | Slow-growing varieties include Cordyline Raspberry Fountain, which grows to a maximum height of 75 cm. Green-leaved varieties are the fastest-growing, reaching around 5 metres high. Coloured and variegated varieties are less vigorous and rarely grow larger than 2.5-3 m high. |
| Hardiness | Cordyline australis is the hardiest species and should survive outdoors in mild parts of the UK, especially in a sheltered spot. However, young plants and cultivars with coloured foliage are susceptible to winter damage. |
| Soil | Cordylines like fertile, well-drained soil. |
| Sunlight | Full sun is ideal for green-leaved cordylines, but light shade is preferable for those with colourful or variegated leaves, as strong sun can fade their hues. |
| Watering | Cordylines require little watering once established. When grown in containers, they need regular watering and feeding, and winter protection, except in mild areas. |
| Propagation | Cordylines can be grown from seed, but this takes years. They can also be propagated from suckers, which are shoots that arise from the base of the plant. |
| Pruning | Cordylines can be pruned to shape the plant and encourage bushier growth. |
| Root system | Cordylines typically have a shallow, fibrous root system, making them well-suited for growing in containers. However, some species, such as Cordyline australis, can have more aggressive root systems and become invasive in some areas. |
| Temperature | Cordylines prefer warm, humid environments and can tolerate a wide range of temperatures, typically between 18°C and 29°C. They are sensitive to frost and should be protected or brought indoors during cold weather. |
