Clematis "Empress" aka ' Evipo 11' ,a Sport of "Evijohill' also known as 'Josephine'
has been growing in my garden for two years, She is a beautiful pink with a big pink boss. She blooms heavily in late Spring and again from me in later September/Oct . This Clematis is from the Evison/Poulsen 'Regal' Collection. I hard pruned her the second year as I do all my Pruning group 2's to allow them to get a better root system...I will not prune her again like that and treat her as a Pruning group 2 from now on...She is one of my Favorites...Jeanne
