I purchased a Barbara Harrington and I has been reading and some vendors call her a prunning group 2 and some are calling her a group 3. Clematis A - Z calls her a group # 3. If any one her has her which group do ya'll prune her at? and which does she do best at? I will hard prune her for the first several years since she was just ordered a couple weeks ago. Look farward to hearing about Ms. Barbara.
