Patti,
I thought for some reason you had a Rose of Sharon along with your Hibiscus moschuetos. The Rose of Sharon that I have (just one) never throws off any new plants anywhere, wish it did, lol. I was told you have to have more than one of these plants to get any seed pods.
Anyway, thanks for the information! I tried growing a dinner plant sized red one like your white one once, not sure of the name (Walmart special) and it died during the winter, that was years ago and I haven't bought another one, but do love them.
I'm not even sure if there is one that could withstand our cold winters
Good luck with your white dinner plates!
Susan
