Thunbergia Germination Information

Thunbergia Seed Germination How to Sow Thunbergia:
  • Best sown indoors, 6-8 weeks before last frost, at alternating 68 and 86°
  • Expect germination in 10-15 days
  • Seeds can also be sown outdoors, after all danger of frost has past in the spring
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Thunbergia:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Site 1 foot apart in full sun or light shade in an acidic to neutral, light, rich, moist, well-drained soil

Temperature: The plants do not like excessive heat and will flower best when summer is a bit cooler

Additional Care: Feed monthly with a high phosphorus fertilizer. Tolerant of humidity, pollution, exposure, and wind

Appearance and Use:

The following are climbing vines for covering fences, posts, stakes, or any small structure. As short vines, to 6 feet long, they can also be planted in hanging baskets and window boxes and be allowed to trail downwards. They have dark green, arrowhead-shaped leaves and when grown outside are covered in flowers from summer to fall (when the weather is cooler); in the greenhouse they flower in the winter. Thunbergia alata has 11/2 inch, tubular flowers in white, orange, or yellow—all with black throats. Thunbergia gregorii has 21/2, tubular, deep orange-red flowers without black throats
