    The description on my plant tag, from Donahue's Clematis, reads:
    The 2" bell-shaped flowers are intense deep blue/purple with lighter blue recurved petals. Flowers fade to indigo blue. Blooms June-September. Shade roots to keep roots cool and moist."

    This variety and Sweet Autumn Clematis are the best Clematis I have ever grown in my no fuss garden. It blooms just about non stop throughout the growing season. VERY carefree and easy to grow!
