Growing Guide

When to Grow

Soak the seeds for 24 hours, then sow them indoors about 6 weeks before your last frost date, and have a fence or trellis ready - this mix is a vigorous climber. Thunbergia wants heat and humidity. Full sun gives the heaviest bloom in most regions; in the hottest climates, some afternoon shade keeps the foliage from scorching. Bloom runs from midsummer until frost, and in USDA zones 9 and warmer the plants will perennialize.

How to Sow and Plant

  • Seeds germinate in 7-14 days.
  • Soak seeds for 24 hours before planting to hasten germination.
  • Sow seeds indoors 6 weeks before last frost.

How to Grow

  • Thunbergia is a tropical climbing vine that prefers partial/dappled shade, heat and humidity.
  • Space plants 8-12 inches apart.
  • Plants cannot tolerate blazing full sun. They will sunburn, so it is important to keep the plants protected from all-day full sun.
  • Provide a trellis for the vines to climb.
  • Afternoon shade is ideal.

PESTS/SPECIAL CONSIDERATIONS

No particular pests or diseases.

How to Save Seeds

Seeds are easy to save if you catch them before they fly across the garden!

  • The mature seeds of thunbergia will spring open and disperse sometimes feet away from the plant (this is how the plant evolved to travel and spread!).
  • When your flowers bloom, allow the flowers to die off and turn brown. You will see a yellowing pod that has a long, pointed tip and round base. Allow it to dry partially before bagging it with a little piece of cheesecloth or paper bag, whatever you have on hand. This bagging will capture the seeds before they explode across the garden.
  • Dried seed pods can be cracked open to reveal 2-3 small, round black/brown seeds.
  • Store in an airtight jar or plastic bag. Store seeds in a cool, dark, dry place.
