Cabbage tree (Cordyline australis 'Salsa')

Overview

Cordyline australis ‘Salsa’ is a visually dynamic cultivar of the well-known Cabbage tree, prized for its compact size and richly colored foliage. This selection distinguishes itself with linear leaves sporting deep red-purple tones accented by contrasting pink midribs and margins, bringing a vibrant tropical feel to any setting. While the parent species, Cordyline australis, can reach impressive heights in mild climates, ‘Salsa’ remains manageable, making it an excellent choice for container gardening year-round. Its low maintenance needs and tolerance for varied conditions solidify its popularity as a reliable accent plant.

This particular form of the Cabbage tree usually matures to a modest 2 to 3 feet tall and wide, perfect for placement on patios or as a dramatic temporary houseplant where it can be protected during colder months. Gardeners appreciate the fountain-like habit of the young plants, which slowly develops into a small, cane-like trunk over time. For consistently successful cultivation, especially outside its hardiest zones, providing the proper container environment is key to enjoying the rich hues of Cordyline australis ‘Salsa’.

How to Grow

When planting Cordyline australis ‘Salsa’, ensure it resides in a container, as it is only reliably hardy in USDA Zones 9 through 11. If growing outdoors seasonally, place it where it receives full sun to light part shade. Although its native habitat tolerates boggy to dry soils, cultivated specimens, especially in containers, perform best in moist, fertile, organically rich, well-drained media.

Watering requires attention, particularly based on location. Keep container soils consistently moist throughout the active summer growing season. When overwintering indoors as a houseplant, reduce moisture significantly during the winter months, allowing the soil surface to dry slightly between waterings.

Container plants should be provided ample root space; this species develops a significant taproot necessitating a large, deep container for optimal development. Patio plants must be brought indoors before freezes occur and overwintered in bright, sunny locations or sheltered within a greenhouse to survive colder periods outside of Zones 9-11.

Landscape Uses

The compact nature of Cordyline australis ‘Salsa’ makes it supremely versatile, especially in regions where winter protection is mandatory. It excels as a focal point in summer patio displays, adding immediate vertical interest and bold color contrast against lighter foliage plants. Mature container specimens bring a distinctly tropical flavor to decks, balconies, and entryways.

Use this colorful Cabbage tree to pair with silver or chartreuse-leafed annuals for maximum impact in mixed container arrangements. As a houseplant, it serves well as a permanent architectural accent or during winter months when outdoor planting is impossible. Focus on placement where its dark red-purple leaves can contrast strongly with surrounding greenery.

Noteworthy Characteristics

Cordyline australis, commonly called giant dracaena or cabbage palm, is one of the best known and most recognized of the plants indigenous to New Zealand where it typically grows as a single or multiple-trunked tree to 20-30’ tall. It was introduced into the U.S in the early 1800s and now grows in a number of locations in California and the southern U.S. It features sword-shaped gray-green leaves to 3’ long and only 2-3” wide. Impressive panicles of small fragrant white flowers bloom in late spring to early summer, however container-grown plants rarely flower. Young plants feature a fountain of grass-like leaves with no trunk and are often sold in this form as houseplants. Patio container plants will slowly develop a cane-like trunk or trunks over time, eventually growing to as much as 15’ tall. Synonymous with Dracaena australis.Genus name comes from the Greek word kordyle meaning a club.Specific epithet means southern.‘Salsa’ is a selection of giant dracaena that features dark red-purple, linear leaves with contrasting pink midribs and margins. Mature plants will reach up to 3’ tall with an equal spread. Plant patent number PP26154 applies to this cultivar.

Companion Planting in Containers

Since this plant thrives in containers, pairing it successfully relies on complementary textures and colors that share similar moderate water and light needs. Combine Cordyline australis ‘Salsa’ with trailing silver foliage plants like Dichondra argentea ‘Silver Falls’ to enhance the pink margins of the leaves. Alternatively, use bright green or chartreuse foliage plants like creeping Jenny to provide a stark, high-visibility backdrop that lets the dark tones of the Cabbage tree truly stand out. Ensure all plants share the need for moist, well-drained soil to simplify watering routines.

Container Growing Best Practices

Success with Cordyline australis ‘Salsa’ relies heavily on root management due to its strong taproot system. Always select a container that is significantly deeper than it is wide to accommodate this growth habit, preventing the plant from quickly becoming root-bound. Good drainage is non-negotiable; ensure the pot has ample drainage holes, using high-quality potting mix amended with compost for fertility and structure. Flushing the soil thoroughly with water periodically helps prevent the buildup of mineral salts, which can stress foliage-focused plants like this Cordyline.
