Clematis 'Rooguchi', Non-vining Clematis

People always exclaim when they see these two-inch cobalt-blue bells with recurving petals that obligingly bloom from late spring and on into early autumn! This non-vining, multi-stemmed clematis winds its way through a (compatibly colored or perhaps less interesting) shrub, or tied on to a support structure it's a charming addition. Mature size: 8 ft T x 3-4 ft W Minimum temperature: -40° F
