Tradescantia sillamontana variegata, Variegated Cobweb Spiderwort

Size: Single Plant | 2.5″ Pot Included

Tradescantia sillamontana variegata, also known as Variegated Cobweb Spiderwort, White Velvet Plant, or Teddy Bear Vine, is a popular houseplant known for its unique velvety leaves with striking green, cream, and pink variegation. It’s a relatively low-maintenance plant, making it a good choice for beginners.

Here’s a comprehensive guide to caring for your Tradescantia sillamontana variegata:

1. Light:

• Bright, indirect light is ideal. This will help maintain the vibrant variegation and prevent the plant from becoming leggy.
• It can tolerate some direct morning sun, but avoid harsh afternoon sun, which can scorch the delicate leaves.
• If the variegation starts to fade, it might not be getting enough light. If leaves are burning, it’s getting too much direct sun.

2. Watering:

• As a succulent-like plant, Tradescantia sillamontana is drought-tolerant and sensitive to overwatering.
• Allow the top 1-2 inches of soil to dry out completely between waterings.
• Water thoroughly until water drains from the bottom of the pot.
• Reduce watering frequency in winter when the plant’s growth slows down.
• Overwatering is the most common cause of root rot in this plant.

3. Humidity:

• Tradescantia sillamontana variegata adapts well to normal room humidity.
• While it can tolerate lower humidity, moderate to higher humidity will create a fuller, happier plant.
• You can increase humidity by:
  • Placing a pebble tray with water beneath the pot (ensure the pot isn’t sitting directly in the water).
  • Grouping plants together.
  • Using a room humidifier.
  • Misting occasionally, but be mindful of the fuzzy leaves; excessive moisture on the foliage can lead to issues.

4. Soil:

• Well-draining potting mix is crucial to prevent water retention and root rot.
• A mix formulated for succulents or cacti is excellent.
• A good homemade mix could include:
  • Regular potting soil
  • Coarse sand
  • Perlite or pumice (in equal parts)
• Adding organic matter like well-rotted compost or worm compost can improve nutrient content and soil structure.

5. Temperature:

• This plant prefers moderate temperatures, ideally between 15-27°C (60-80°F).
• Protect it from cold drafts and extreme temperature fluctuations.
• It is winter hardy in zones 10-12 and should be brought indoors if temperatures drop below 10°C (50°F).

6. Fertilization:

• During the growing season (spring and summer), you can fertilize monthly with a balanced, diluted liquid houseplant fertilizer.
• Alternatively, a slow-release fertilizer can be incorporated into the potting mix.
• It’s better to under-fertilize than over-fertilize, as this plant can thrive with minimal feeding if other needs are met.
• Always water the plant before fertilizing to prevent root burn.

7. Pruning:

• Prune regularly to maintain shape and encourage bushier growth.
• Pinching back the tips will promote a denser habit.
• After flowering, cutting back the plant can encourage a second bloom and prevent self-seeding.
• Remove any dense, diseased leaves or old stems to ensure good air circulation.

8. Propagation:

• Tradescantia sillamontana variegata is very easy to propagate, primarily by stem cuttings.
• Water propagation:
  • Take a stem cutting that is at least 4-6 inches long with several leaves.
  • Remove the lower leaves so that the nodes (where leaves were attached) are bare.
  • Place the cutting in a container of clean water, ensuring the nodes are submerged.
  • Change the water every few days. Roots typically form quickly (within 1-2 weeks).
• Soil propagation:
  • Take stem cuttings as above.
  • Plant the cuttings directly into a well-draining potting mix, ensuring a few nodes are buried.
  • Keep the soil consistently slightly damp until roots establish.
• You can also try layering, where you bend a healthy stem down to the soil surface, cover it with soil, and once roots form, cut it from the mother plant.

9. Pests and Diseases:

• Monitor for common houseplant pests like aphids, spider mites, thrips, and mealybugs.
• Root rot can occur from overwatering.
• Leaf scorch can result from too much direct sun.

10. Toxicity:

• Be aware that Tradescantia sillamontana is toxic to humans and pets if ingested. Keep it out of reach of children and pets.
• Handling the plant can also cause skin redness and irritation, so wearing protective gloves is recommended.

With its beautiful variegated foliage and relatively easy care, Tradescantia sillamontana variegata makes a charming addition to any indoor plant collection, especially in hanging baskets or as a trailing plant.
