The Q&A Archives: Saving Zinnia Seeds

Question: I'm growing Burpee's "Cut and Come Again" Zinnias. They are so beautiful and a joy to behold. I grew them from the seed tape. As far as I know, Zinnias are annuals. How do I harvest the seeds? Where are they located? Do they self-seed?

Answer: That is one of my favorite double zinnias, too. They are considered annuals and as such need to be started each year. The seeds form inside the flower head once the petals fade and the ripening process is completed. Usually the seeds are mature when the spent flower is completely dried up. The seed tends to stay stuck in the flower form, so you may need to pull it apart gently to separate them. In my garden this type will self seed but not very well -- over time the more unusual colors seem to disappear, among other things so it is really more "true" if repurchased. Enjoy your zinnias!
