Clematis

70524There are so many different specie involved with the extensive breeding of the modern cultivars of clematis that they are not even assigned full Latin names. They are simply known as ‘clematis’ (without a specie name), with a respective cultivar name. Clematis X jackmanii is the oldest known hybrid, so the name is often applied to other hybrids, whether or not they are actually related.

The big broad flowers are abundant and spectacular this time of year, but unfortunately do not last long. Bloom finishes before the weather gets much warmer, leaving unimpressively rustic foliage on wiry vines. The vines might reach ground floor eaves, and are just the right size for small gate arbors. If necessary, old plants can be lightly groomed of twiggy growth while bare through winter.

Flowers are rich shades of blue, purple, red, pink or white. Many are bi-colored, and some have ruffled centers. During full boom, there may be more flowers than foliage visible. Foliage is a dark shade of olive green, with a dull matte finish, which is actually a perfect background for the rich color of the bloom. Roots like rich, moist and cool soil, while the vines climb into sunnier situations.
