I know some people who would look with scorn at the subject of my last post. Clematis 'Cassis' is, for them, too overbred, too complex and in the worst possible taste. For them, the simplicity of the species, unmixed with the genes of others, is the only choice.
I am unrepentant in my love of the big and bold and complex structure of double flowers, I also have to admit to loving with equal affection the unaffected beauty of species as well as the inherited qualities of the 'primary hybrids'. Since we are in the middle of Clematis season here are some of my favourites.
Clematis adisonii ,a species found in the mountains of Virginia , USA.
The lovely seedhead of C. addisonii.
Clematis 'Odoriba', a C. viorna x C.crispa cross.
Clematis 'Sonnette', derived from C. viorna. In the UK it is known as 'Peveril Peach'.
Clematis 'Harlow Carr', Clematis on the Web mentions that the origin is withheld by hybridizer, but it must have C. integrifolia as one of its parents.
Clematis 'Betty Corning', thought to be C. crispa x viticella.
