Clematis koreana Blue Eclipse

Clematis Blue Eclipse

This is a wonderfully elegant, non-evergreen climber which seems to be particularly attractive to bees and butterflies.

Clematis koreana 'Blue Eclipse' has the most delightful, small blue, cream-edged nodding bell-shaped flowers of a thick, fleshy texture, that are speckled with cream on the outside and have double cream centres.

The flowers are long lasting and freely produced during the spring, giving way to attractive silky seed heads. A second flowering may occur in August.

Clematis koreana 'Blue Eclipse' was raised and introduced by Vince and Sylvia Denny, England, in 1987.
