Empress™ is sure to empress with its unique flowers that nearly cover the vigorous vine from Late spring into the fall. Most class 2 clematis take a break in the summer as the flowers formed on the old wood fade and the new wood buds are developing, not with Empress™, the bloom just keep coming and coming! A truly great introduction from Raymond Evison! Plant this charming Clematis in a sunny location where the roots can keep cool with plenty of mulch and some shade.
