Tradescantia pallida, commonly called Purple Heart, is a trailing, succulent-like perennial prized for its saturated violet foliage and forgiving nature. Native to northeastern Mexico, it forms dense mats by rooting readily at nodes along fleshy, burgundy to purple stems. Lanceolate leaves, often 10–15 cm long, are velvety beneath and develop deepest coloration in strong light as anthocyanins accumulate. Small, three‑petaled, pink to lavender flowers appear intermittently at stem tips in warm, bright conditions. Indoors it excels in containers and hanging baskets; outdoors it serves as a vivid groundcover in frost‑free climates. Expect 20–40 cm in height with a spread of 60–90 cm or more. It tolerates short dry spells and heat yet prefers regular moisture in a sharply draining medium. Frequent pinching promotes bushiness and prevents legginess. In some warm regions it can naturalize vigorously; dispose of trimmings responsibly to avoid escape beyond the garden.

How to care for Purple Heart
Water
Allow the top 2–3 cm (about 1 inch) of soil to dry between thorough waterings, then irrigate until excess drains freely. In bright, warm conditions this may be once or twice weekly; in winter or low light, reduce to every 10–14 days. Avoid chronic sogginess to prevent root rot and dull coloration. Bottom-water occasionally to ensure even hydration, and flush the pot monthly to remove accumulated salts, especially when using hard tap water.
Light
Provide bright light with several hours of gentle direct sun daily for best color—an east or west window is ideal, or a south window with sheer curtains. Outdoors, give morning sun and afternoon shade in hot climates; full sun is tolerated where summers are mild. Low light leads to leggy growth and greener leaves. Acclimate when increasing light intensity to prevent bleaching, and aim for 4–6 hours of bright light to maintain rich purple tones.
Nutrients
Feed during active growth (spring to early fall) with a balanced fertilizer at 1/4–1/2 strength every 4–6 weeks. Excess nitrogen can encourage lanky, greener growth and reduce purple intensity, so favor balanced or slightly higher potassium formulas. Use a fast-draining substrate and flush with plain water every 6–8 weeks to prevent salt buildup. Pause fertilizing in winter or in low light when growth slows, resuming once days lengthen and new growth appears.
Temperature
Ideal temperatures are 18–29°C (65–85°F). Protect from chill below 10–13°C (50–55°F) and bring containers indoors before frost; freezing (0°C/32°F) kills foliage and may damage crowns. In USDA Zones 9–11 it can grow outdoors year-round; in Zone 8 it may resprout after light freezes if mulched. It tolerates heat with adequate water and airflow, but sustained temperatures above 35°C (95°F) in full sun can scorch leaves, especially if the substrate dries out.
