they will produce a tuber per plant so in the autumn bring them into a frost free place and let the tubers die back. I tend to lay them in their pots on their side. Then in the spring I repot them in fresh compost and get them growing again.
they may produce seed again but they may not be like these as they are a variety. But a wonderful voyage of discovery.

Do they grow from tubers, if so you can keep them frost free for next year and take cuttings too, they will be like the parent, seeds are fun too, you never know quite what you will get
