Early Large Flowered, Group 2.
Blue, white anthers. 6 to 8 petals. Average diameter 8". Single bloom form. Late spring to early summer, early autumn.
Height of 8' to 12' (245 to 365 cm).
USDA zone 4b through 9b. Plant in sun or partial shade. Suitable for growing in a container. Disease susceptibility: clematis wilt. This plant blooms twice. It blooms on the previous year's growth, so resist the urge to prune it in early spring. However, if you garden in a place with cold winters, Mother Nature will more than likely prune the plant for you. It will bloom a second time on new growth.
