anyone successfully overwinter hibiscus?
A friend recently purchased a hibiscus from Menards. I don't recall the variety name, but it was beautiful and labeled hardy to zone 5.
I don't know of anyone personally who has ever successfully overwintered any hibiscus in zone 5. I know of several who have tried without success.
So, what's your experience Wisconsinites? Anyone have success? If so, how do you protect them and what variety worked?
