Light and placement

Provide full sun to partial shade. In cooler climates, use a south- or west-facing, sheltered position; in hot inland areas, bright morning sun with protection from intense afternoon heat can preserve the pink margins. Too little light produces weaker, greener growth, while excessive harsh sun may scorch leaves, especially after indoor cultivation.

Watering and humidity

Water thoroughly when the upper layer of soil has begun to dry, then let excess drain away. Keep newly planted specimens evenly moist while establishing, but reduce watering in cool weather and winter. Established plants tolerate short dry periods; the main risk is crown or root rot from saturated soil.

Soil and growing medium

Use a free-draining mix or soil containing loam, sand, grit, or other mineral material. The plant tolerates a broad pH range, but persistent waterlogging is more damaging than modest acidity or alkalinity. Container plants need drainage holes and should not sit in standing water.

Feeding

Feed in spring and summer with a balanced, complete fertilizer at label strength or slightly weaker for containers. Water the soil first if it is dry, and reduce or stop feeding in late fall and winter when growth is slow. Excess fertilizer can worsen salt buildup and marginal leaf damage.

Growth and habit

Forms a persistent rosette that may develop a woody, palm-like trunk with age. Plants can remain compact in containers but become more tree-like when established outdoors. Mature stems may branch after flowering or damage, so allow recovery space and remove only clearly dead foliage.

Planting

Planting and repotting

Planting timeSpring after hard-freeze risk; early fall in frost-free areas
Planting depthPlant at the same depth as the root ball; do not bury the crown
SpacingAbout 3–4 feet between landscape plants, adjusted for climate and desired fullness

Plant outdoors in spring after the danger of hard frost, choosing a sheltered site with good drainage. Set the root ball level with the surrounding soil and firm gently. Allow enough room for the rosette to develop without crowding nearby paths or walls.

Repotting

Repot container plants in spring when roots fill the pot or growth slows. Move up only one pot size, use a sharply draining mix, and avoid burying the stem or crown deeper than before. Large specimens can be top-dressed instead of repotted.

Practical tasks

Propagation and pruning

Propagation

Commercial production commonly uses tissue culture; home growers may use well-rooted basal offsets or stem cuttings when available. Take cuttings in active growth, keep the medium warm and free-draining, and expect rooting to be slower than with soft herbaceous plants.

Pruning

Little pruning is required. Remove dead or badly damaged leaves at their base, and cut off spent flower panicles after flowering if desired. If a stem is killed by cold, wait until spring to assess living tissue before cutting back to healthy growth.

Seasonal care

Overwintering

In USDA Zones 9–11, protect plants from unusually hard freezes with frost cloth and a dry, sheltered position. In colder zones, grow in a container and overwinter indoors in bright light, watering sparingly. Avoid placing the plant beside a heat vent, and acclimate it gradually when returning outdoors.

Practical use

Uses

Best used as a foliage specimen, patio or balcony container plant, sheltered border accent, poolside feature, or architectural planting in warm climates. It can be moved indoors for winter in colder regions. Do not use as an edible plant, and prevent pets from chewing it because the species is toxic to dogs and cats.

Identification and habit

Appearance

The cultivar forms a bold rosette of long, arching, sword-shaped leaves. Foliage combines gray-purple or burgundy tones with bright pink margins and narrow contrasting striping. Older plants may develop a stout, palm-like trunk, making the plant recognizable as a cordyline rather than a true palm.

Flowering

Flower sizeSmall

Mature plants may produce terminal panicles of numerous small, white, fragrant flowers, generally from late spring into summer in climates where they can remain outdoors year-round. Flowering is less dependable in containers and on young plants. Spent panicles may be removed for tidiness.

Ecological relationships

Pollination and visitors

Its fragrant white flowers can be visited by bees, hoverflies, and other small insects. The cultivar is mainly grown for foliage, and flowering may be infrequent in containers or before plants reach maturity.

Plant protection

Diseases and pests

Diseases

Usually trouble-free when drainage and airflow are good. Root or crown problems are most likely in persistently wet soil. Improve drainage, avoid overwatering, remove damaged tissue with clean tools, and discard severely rotted container plants rather than reusing contaminated mix.

Pests

Scale insects and glasshouse red spider mite may occur, especially on stressed or indoor plants. Inspect leaf bases and undersides regularly, isolate affected containers, wash foliage where practical, and use horticultural oil or another labeled treatment according to its instructions. Avoid treating drought-stressed plants.
