Tradescantia sillamontana, popularly called White Velvet or Cobweb Spiderwort, is a small, semi-succulent perennial native to the arid highlands of Mexico. Its upright, zig-zag stems carry rounded olive-to-purplish leaves that are completely wrapped in silvery-white cobweb-like hairs, a feature that protects it from harsh sun and reduces water loss.
In Indian homes it is grown as an ornamental potted plant for bright balconies, windowsills and shaded terraces. Through the warm months it produces small bright magenta-pink three-petalled flowers at the stem tips. Tolerant of heat and neglect, it suits beginners looking for an unusual textured succulent.

Care guide
| Sunlight |
Bright light; a few hours of gentle morning sun. Best colour and dense hairs in bright spots, but protect from harsh afternoon sun. |
| Watering |
Water only when the top 2-3 cm of soil dries; let it dry between waterings. Reduce sharply in winter. Avoid soggy soil to prevent rot. |
| Soil / mix |
Free-draining gritty mix; standard potting soil amended with sand, perlite or cocopeat in a pot with drainage holes. |
| Temperature |
Thrives at 18-32 C. Tolerates Indian summer heat; protect below 7-10 C and from frost. |
| Humidity |
Prefers low to moderate humidity; tolerates dry indoor air well. Avoid misting as wet hairs invite rot. |
| Fertilizer |
Feed lightly with a balanced or cactus liquid feed once a month during the growing season; skip in winter. |
| Pruning |
Pinch back leggy stems to keep the plant compact and bushy; remove faded or rotten growth. |
| Repotting |
Repot every 1-2 years in spring when crowded; refresh soil and move up one pot size. |
| Propagation |
Very easy from stem cuttings; let cut ends callus a day, then root in moist gritty mix. |
| Pests & problems |
Generally pest-resistant; watch for occasional aphids, mealybugs or spider mites, and root rot from overwatering. |
| Toxicity / safety |
Mildly toxic if eaten and the sap can irritate skin; keep away from pets and small children. |
| Difficulty |
Easy |
Uses
White Velvet is grown chiefly as an ornamental for its unusual furry silver foliage.
- Tabletop, windowsill and bright-balcony pot plant
- Textural filler in succulent dish gardens and mixed arrangements
- Hanging baskets where stems can trail and spread
- Low-care greenery for offices and beginner gardeners
Growing tips
Give it the brightest spot you can without scorching afternoon sun; bright light keeps the white hairs dense and stems compact.
During the dry season water sparingly and let the mix dry out fully between waterings. In the monsoon, shift pots under cover and ease off watering to avoid rot. Pinch the tips through summer for a bushy plant, and take cuttings in spring or the post-monsoon warmth when they root fastest.
