In an open aspect to the south of the rock garden two Clematis are flowering. Clematis ternifolia, a vigorous grower with lightly scented white star like flowers bearing linear petals. A native to eastern Asia. Prolific in flower it attracts the attention of garden visitors and pollinating insects alike. Adjacent is Clematis campaniflora native to southern Europe; the Iberian Peninsula. With an entirely different floral shape. These light violet petals are fused to resemble a bowl with tips recurved, held singly on the stem in a pendulous manner. Both can be cut down to the base in early spring to allow regeneration growth to appear. Given support; a height of 8 – 10 metres can be reached.
