Cordyline, commonly referred to as Ti Plant or Good Luck Plant, is a captivating genus of tropical and subtropical plants renowned for their striking foliage. The genus includes around 15 species, each boasting unique leaf shapes, sizes, and colors. Cordyline plants are prized for their ornamental value and are popular both as houseplants and garden specimens.
Cordyline thrives in bright, indirect light to some direct sun. The more colourful varieties (red, pink, tricolour) require brighter light to maintain their intense pigmentation. Green varieties tolerate moderate shade. Direct intense midday sun scorches the long, strap-like leaves.
Allow the top 2–3 cm of soil to dry between waterings, then water thoroughly. Cordyline prefers consistent moderate moisture — it does not tolerate prolonged drought or waterlogging. Like Dracaena, it is sensitive to fluoride in tap water, which causes brown leaf tips. Use rainwater or filtered water where possible.
Well-draining, fertile potting mix with added perlite (3:1). Slightly acidic pH (6.0–6.5).
Cordyline fruticosa (the most common indoor species) prefers 18–27 °C and is cold-sensitive. Cordyline australis is much more cold-hardy (to -5 °C) and is suitable for outdoor use in mild climates. Standard indoor humidity is adequate; dry air contributes to brown tips alongside fluoride.
Feed monthly during spring and summer with a balanced liquid fertilizer at half strength. Reduce in autumn, stop in winter.
Remove old leaves at the base as they naturally yellow and die. Cordyline grows from a central trunk and does not branch unless the top is removed. If it becomes too tall, cut the main stem to the desired height — new shoots will emerge below the cut. Contains compounds mildly toxic to cats and dogs.
The most common method for propagating Cordyline is by cuttings. This involves taking a section of the stem and rooting it. Ensure the parent plant is healthy before proceeding.
Some Cordyline species produce offsets, or "pups," which can be separated from the parent plant and potted individually.
