From midsummer to autumn, a sucession 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.
- Garden care: In early spring cut back the previous year's stems to a pair of strong buds about 15-20cm (6-8in) above ground-level and apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the plant, avoiding the immediate crown.
