Rainy Side Notes

 

 

Clematis 'Rooguchi' (sometimes spelled 'Rouguchi'), a cross between C. integrifolia and C. reticulata, was initially bred in Japan as a solitary blossom for the Japanese tea ceremony. The late Kazushige Ozawa created an exciting vine for the garden and the floral trade. Floral designers love its two-inch long, glossy purple, bell-shaped flowers.

A non-climbing species, 'Rooguchi' grows eight feet tall when tied onto an arbor or left to crawl through a shrub. It is stunning, cascading down a wall, spilling over the top of a fence, or trailing down a tall container. These attributes and its exceptionally long bloom time make it a versatile addition to almost any garden.

Clematis 'Rooguchi' grows best in the maritime Pacific Northwest in full sun or at least five hours of the morning sun, which helps keep the powdery mildew at bay.
