Rainy Side Notes
I believe that Clematis crispa, with its scented flowers, should have been used more in early breeding work.
~Raymond J. Evison
The Delicate stems of this vine hold the utterly charming, bell-shaped, reflexed petals that have variable colors in the wild. You can train this vine to be a shrub, which helps protect its delicate stems. This has a long bloom time, from summer to fall in cold climates, and from late spring into fall in mild winter climates.
This southern native charmer passed its sweet tangerine-like fragrance on to the vine's progeny, C. 'Betty Corning'. Two of its common names—marsh clematis and swamp leather flower—is a testament to where it grows in its native habitats; it is the only clematis that can take wet soil.
Its epithet, crispa comes from the sepal’s wavy or crisped margin. In Illinois where they commonly call it blue jasmine, it’s an endangered species, and in Kentucky where they commonly call it blue jasmine leather-flower, it’s a threatened species.
