How to Collect Seeds from Cypress Vine (Texas Star) and Cardinal Climber
Seeds from both Cypress Vines and Cardinal climbers are easily collected for next year. Varieties will generally re-seed themselves. (The Cypress vine seed collecting is illustrate in this post. The difference between the two plants — Cypress Vine seed pods often bear around 20 seeds, but Cardinal Climbers only bear 1 or two seeds per pod.)
The key is to leave the seeds on the vine until the seed pods are brown (see figures above). To compare Cypress Vine and Cardinal Climber, click to see this earlier post.
Gently crush the brown seed pods to release the tiny dark, oblong seeds. Store in a paper envelope for the next season. Label the envelope with the name of the plant and the date the seed was collected (not shown in the figure).
I generally do not use plastic because it does not “breathe” well, so moisture can accumulate and potentially encourage mold growth.
I create the small envelopes by cutting a long envelope into 3 sections and then taping the open ends.
Happy Seed collecting!
