Variegated forms of Thunbergia mysorensis add an extra layer of interest with their unique leaf patterns. Here’s how to care for a variegated Thunbergia mysorensis:

Care Instructions

1. Light:
   • Prefers full sun to partial shade. Ensure it gets at least 4-6 hours of direct sunlight daily.
   • In hotter climates, some afternoon shade can prevent leaf scorch.
2. Watering:
   • Keep the soil consistently moist, but not waterlogged. Water when the top inch of soil feels dry.
   • Reduce watering in the winter months when the plant’s growth slows down.
3. Humidity:
   • Thrives in high humidity environments. Aim for at least 50-60% humidity.
   • Increase humidity by misting the plant regularly or using a humidity tray.
4. Temperature:
   • Ideal temperature range is between 65-80°F (18-27°C). Protect from temperatures below 50°F (10°C) as it is not frost-tolerant.
   • Can be grown as a perennial in USDA zones 9-11, or as an annual in cooler climates.
5. Soil:
   • Prefers well-draining, fertile soil. A mix of garden soil, compost, and perlite works well.
   • Ensure the soil has good drainage to prevent root rot.
6. Fertilizer:
   • Feed with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring and summer).
   • Use a fertilizer high in phosphorus to promote blooming.
7. Support:
   • Provide a sturdy support structure such as a trellis, arbor, or pergola for the vine to climb. It can grow quite large and heavy, so ensure the support is strong enough to hold the mature plant.
8. Pruning:
   • Prune regularly to maintain shape and control size. Remove any dead or damaged growth.
   • Pruning after the flowering season can encourage new growth and more blooms.
9. Propagation:
   • Can be propagated by seeds or cuttings. Take semi-hardwood cuttings in late summer and root them in a well-draining potting mix.
   • Seeds can be sown in spring; soak them overnight before planting to enhance germination.
10. Pests and Problems:
    • Watch for common pests such as aphids, spider mites, and whiteflies. Treat infestations with insecticidal soap or neem oil.
    • Ensure good air circulation to prevent fungal issues like powdery mildew. Avoid overhead watering to keep the foliage dry.

By providing the right conditions and care, your variegated Thunbergia mysorensis will thrive, rewarding you with its beautiful foliage and striking flowers.
