Cordyline (Cordyline fruticosa, C. australis)—known as ti plant, cabbage tree, or good luck plant—delivers bold, sword-shaped leaves in electric pink, burgundy, green, cream, and chocolate. Native to Southeast Asia, Australia, and Pacific islands, it's a tropical showstopper that adapts to containers indoors or landscape beds in frost-free zones.
Quick Care Summary
| Factor | Requirement |
|---|
| Light | Bright indirect to partial sun. Color intensifies with light. Indoors: east/west window. |
| Water | Consistently moist (not soggy). Top inch dry = water. High humidity loved. |
| Soil | Rich, well-draining. Peat-based + perlite. pH 6–6.5. |
| Temp | 65–85°F (18–29°C). Below 55°F = damage. Not frost-hardy. |
| Fertilizer | Balanced liquid, monthly spring–fall. Potassium sulfate boosts color. |
| Repot | Every 2–3 years spring. Pot up 2 inches. |
Propagation
Stem Cuttings (Fastest)
- Cut 3–5 inch sections from mature cane (include nodes).
- Remove leaves. Dust cuts with rooting hormone.
- Lay horizontally in moist sand/perlite. Cover with bag.
- Warm (75°F), bright indirect. Shoots emerge in 4–8 weeks.
- Pot up when roots + leaves established.
Seeds (For Species)
- Sow in peat moss, cover ¼ inch.
- Warm, humid, bright indirect.
- Transplant at 3–4 inches.
Color Management
- More light = brighter color. But acclimate gradually.
- Potassium sulfate (0-0-50) monthly in growing season enhances pinks/reds.
- Nitrogen-heavy fertilizer = lush green, less color.
Pests & Problems
| Issue | Signs | Solution |
|---|
| Spider mites | Fine webbing, stippled leaves | Hose off; neem oil; increase humidity |
| Mealybugs | White cotton at leaf bases | Alcohol swab; systemic insecticide |
| Fluoride toxicity | Brown leaf tips, margins | Use distilled/rain water; avoid perlite |
| Root rot | Yellowing, wilting, mushy base | Repot in fresh mix; cut water |
Indoor vs. Outdoor
- Indoors: Bright light, humidity tray, rotate. Avoid heat vents.
- Outdoors (zones 10–12): Part shade, wind protection, rich soil. Mulch heavily.
- Overwintering: Bring in before 55°F. Cut water. Bright window.
Cultural Note
In Hawaii, ti leaves wrap food (laulau), make hula skirts, thatch roofs, and ward off evil. Plant at property corners for protection. Every part is useful—roots (starch), leaves (fiber), shoots (edible).
Whether for tropical drama or cultural connection, cordyline rewards attention with unmatched foliage theater.
