A reliable landscape favorite for decades!
Clematis is easy to grow in a rich, porous, alkaline soil with plenty of room for the roots to spread. Best performance is when the tops are in full sunlight and the roots are shaded, so apply a generous mulch or a shallow-rooted ground cover near the base of the vine. Very reliable performers once established, they take a season or two to get going. Henryi is a Group II Clematis for pruning purposes, which means that in early spring you should cut back the vine 6 or 8 inches to the nearest pair of strong leaf axil buds. Zones 3-9.
