Help overwintering Hibiscus acetasello
I have tried unsuccessfully a couple of times to overwinter this tender Hibiscus in my minimally heated greenhouse, but each time it quickly faded away. Has anyone had any success keeping it alive during the winter months? I have rooted about a dozen cuttings of H. acetasello 'Haight Ashbury', and can bring some to the Raleigh plant swap this weekend if you have a warm greenhouse and want to try overwintering it. Of if your are not coming to the swap but are in the Raleigh area and want to try it, email me. For anyone not familiar with this Hibiscus, its foliage looks very much like a dark bronze Japanese maple. Its flowers are insignificant.
