SEED SAVING

Cosmic Candy Mix Black-Eyed Susan Vine

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 which 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.
