The magnificent flowers of Clematis 'Dr Ruppel' are produced in abundance in early summer, with a rose-pink blush along the length of each petal. A second flush in late summer is followed by pretty, spherical seed heads that bring interest to the garden well into the autumn. A compact cultivar, 'Dr Ruppel' is excellent for containers, or for adding a bright splash of colour to a sunny wall. Height: 2.5m (8'). Spread: 1m (3') Pruning group: 2.
