Clematis Happy Birthday (‘Zohapbi’) (PBR)

From midsummer to autumn, a succession of deep purple flowers emerge from silvery buds, gradually fading and taking on a softer, bluish flush as they mature. When both new and old flowers are present on the plant it creates an attractive two-tone effect, which adds greater interest to the overall effect. It looks wonderful scrambling over an obelisk or arch and as it has a relatively compact habit, it is well suited to growing in a large pot.
