We just planted a beautiful Hibiscus Plant from the Biltomore Estate in our garden, purchased at our local nursery. It said full sun and seems to be doing well. The first blooms appeared the other day, beautiful large red flowers. They are beautiful for one day and then droop and wilt the next. Is this normal? I just read online that this plant will not survive a Colorado winter unless we dig it up and bring it inside. My question is: With the drooping blooms...do I pick them off daily...they look so sad!
