I would like to save Canterbury seeds for propagation, but don't know where to find them or what they look like.
Canterbury Bell Seeds

Many of these plants self-seed but if you still want to keep some in the event they don't, just wait until the blooms have dried up and collect the flower heads. Then you can harvest the seeds and plant them right away or save them for planting the next season.
