Wow! We haven't had a frost yet either but my Heartleaf Hibiscus hasn't bloomed in a couple of months...of course, that could be due to deer nips.Are you seeing any hummingbirds? A neighbor has had a couple of Rufous since Thanksgiving and we had a few Blackchinned (male & 2 females) come through a week ago.
Well, actually...I'm cheating, Kathleen. This hibiscus is one of three that I have in pots and I pulled the pots into the garage when the temperature was first expected to go below freezing. But, yes, they are still blooming! My hibiscus in the ground outside - uh, not so much.I haven't had any hummers since just before Thanksgiving, but I've still got my feeders up - just in case.
