Answer: After the petals fall, a seed capsule will form. When it turns from green to a tannish color, the seeds are ripe and ready to harvest. Carefully cut the seed pod from the flowering stem then hold it over a jar or plastic baggie and gently squeeze it open. You'll see what looks like a seam running the length of the seed pod, and that's where the two halves will open. Direct the seeds into your container (they're very small!), then seal the container and store it in a cool, dark location until it's time to sow them next spring. It's important that the seeds are completely dry before storage. If in doubt, leave the top off the jar or the baggie open for a few days before sealing and storing. Since Foxgloves are biennials, expect vegatative growth the first year and flowers the second year.
