Tradescantia Zebrina: Purple, Striped, and Growing Faster Than You Can Keep Up
A fast-trailing vine with silver-striped leaves and purple undersides that roots from any broken stem. Bright indirect light keeps the color; pinch often to keep it full.
Tradescantia zebrina, the silver inch plant (or “wandering dude”), has leaves striped in silver and green with a rich purple underside that glows when the light hits it. It grows an inch or more a week (hence the name), trails beautifully from a hanging basket, and roots so easily that a broken-off stem stuck in soil will just… keep growing. It’s practically impossible to run out of.
Where to put it (light)
Bright, indirect light gives the boldest stripes and purple. A little direct morning sun is fine. In low light the color fades to plain green and the stems stretch and get sparse.
Temperature
60–80°F (16–27°C). Tolerates down to 50°F (10°C). Keep it away from cold drafts.
Watering
Water when the top inch of soil is dry. It likes lightly moist soil and wilts when thirsty, but soggy soil rots the stems. Avoid getting water on the leaves; it can leave marks.
Feeding
Monthly in spring and summer with a balanced liquid fertilizer at half strength. Over-fertilizing dulls the stripes.
Soil
Standard well-draining potting mix with a bit of perlite. It’s not picky.
Humidity
Average household humidity is fine; it’ll appreciate a bit more but doesn’t demand it.
Common pests
Aphids, spider mites, and mealybugs. Fungus gnats in wet soil. Because it grows so fast, the easiest fix for any problem is to cut healthy tips and start over.
Propagation
Difficulty: Very easy. Stem cuttings. Snip 3–4 in (8–10 cm) tips, strip the lowest leaves, and stick them in water or directly into moist soil. Roots in about a week.
Also worth knowing
Toxicity: sap can irritate skin and it’s mildly toxic to pets. Mature size: trails 2–3 ft (60–90 cm). Repot yearly or simply restart from cuttings when it gets leggy.
Pinch it back often to keep it full; it gets leggy with age. The sap can irritate skin and it’s mildly toxic to pets, so wash your hands after pruning and keep it up high.
