i have two clematis vines. One has single purple petals and the other has a flower that is an off-white color with many rows of petals. I need to divide the later and move the purple. I live in MPLS . I need advice on these lovely vines. Maybe someone could help me identify the names of the particular plants. I can send photos. Thanks a lot.javascript:emoticon(':)',%20'images/emoticons/smile.gif')
