It's a super easy-to-grow clematis with great color and large flowers!

Velvety plum-purple flowers with intriguing center highlights and bright yellow stamens characterize this version of the ever-popular 'Jackmanii' clematis. This early and long-flowering beauty blooms from mid-summer into fall, and is noted for its intense purple flower color and large (3-5" blooms). It flowers on new wood and old wood so you simply prune it back to 2 feet each spring. Winner of a Green Thumb award from the Direct Gardening Association. 

Top three reasons to grow Happy Jack® Purple clematis:
