Red Sister Cordyline also widely known as the Hawaiian ti plant, is a tropical perennial shrub that thrives outdoors in USDA hardiness zones 10 and 11 and indoors as a house plant under mild temperatures and bright, indirect light. Grown mostly as an ornamental, it is famous for its distinctive burgundy pink and bronze-green foliage. However, Red Sister does flower in mid-summer, throwing pale- to medium-pink hued flowers.

Sun Expsoure and Soil Requirements

Red Sister cordyline prefers full sun to partial daily shade conditions and thrives in a rich, well-drained and slightly acidic soil with a pH between 5.6 and 6.5. Amend your planting soil with sphagnum peat moss or aluminum or iron sulfate products tilled into the soil, according to the manufacturers specifications.

Watering Requirements

Though a tropical plant, cordyline does not require overly moist soil or wet roots. Keep the soil evenly moist, when reaching 1 inch down into the soil. Make sure the container has drainage holes, so that the roots are never in standing water for any length of time.

Pruning and Fertilizing

Cordyline is low-maintenance when it comes to pruning. Cut away any diseased or damaged leaves with clean, sharp secateurs. Fertilize both ground planted and indoor and outdoor container plants with a high-quality, water-soluble general fertilizer at least three times a year. If you use rich garden compost amendments to your soil, cut down feedings to twice a year.
