Clematis ‘Ocean Pearl’ is a striking clematis from the Atragene group and flowers from April to May with single and double light blue flowers of 5 to 7 centimetres followed by attractive seed pods with a long vase life and grows to 250 to 300 centimetres in height. The white stamens of the single flowers are like pearls on a background of ocean blue petals. Clematis ‘Ocean Pearl’ can be slightly pruned back after flowering in June and prefers a well-drained habitat.
