Where are the seeds located on vining black eyed susan plants? I have two and they are doing really well and would like to have the seeds to grow next year. I saw a video but my plant does not have the kind of shoot it was saying. I am in the 5 and 6 zones. Thank you for any information.

Seeds slowly develop at the base of the flower, usually in a pod. It takes several weeks for seeds to mature. The pod turns brown when they are ready. If you don't have any seed pods, it may be you have a sterile cultivar or the flowers are not being pollinated. Have you looked at google images of Thunbergia seed pods?
