I got this Hibiscus and another one at Wal-Mart on clearance, though I don't know if the other one is the same color, because it has never bloomed. They're doing quite well, overall and have filled out a lot since this picture was taken, but this was one of only two blooms this one has had. Both are full of buds, but the buds and stems they're on turn yellow and fall off before they open. Could you please ID this for me and give me some idea of what's causing all the buds to drop off? I also need to know if I should bring them in over the winter, or if it's hardy in my Zone, but can look that up once I know what this one is and I'll treat the other the same way until I can ID it.
Thanks for your help!
