What are Clematis Flowering Vines?



    • Clematis vary in height from small plants that grow just 2 to 5 feet, to vines that reach 30 feet, according to the Clemson University Cooperative Extension. Flower forms range from small clusters and bell-shaped varieties of species clematis to the familiar large, open blooms of hybrids. Flower hues include white, pink, purple, red and yellow. Species clematis tend to be one color, but some hybrids come in color combinations.


    • Growers divide clematis into three main groups, according to Reiman Gardens. Early flowering clematis bloom from April through June from buds formed the prior season. Examples include C. alpina and C. macropetala. The second category are clematis that bloom twice, such as 'Ramona' and 'The President.' This group flowers in May or June from last year's growth, and again in late summer on current season growth. The third group of clematis bloom on current season growth from late May to September. 'Ernest Markham' and 'Hagley Hybrid' are in this category.
