Like Ginger and MaryAnn, choosing between the flashier hybrids of clematis and the anemone clematis, Clematis montana, might not be so easy. The fancier hybrids have the bigger, bolder and richly colored flowers that the genus is known for. Anemone clematis has smaller and more subdued flowers in soft pastel hues, but is more prolific, more vigorous, and blooms for nearly a month.
The simple spring flowers look something like those of dogwood, except that they are on wiry deciduous vines that are already outfitted with new foliage. Most are soft white with only four petals and prominent yellow anthers. Some are blushed, pale pink, rose pink or pinkish mauve; and some have more petals or fluffier ‘double’ flowers. The largest flowers are a bit wider than two inches.
The vines are more vigorous than those of clematis hybrids, but are not as aggressive as most other vines or winter clematis. With pruning, they can behave on small gate arbors, although shorter trellises would probably be too confining. If vines escape confinement, they can eventually climb more than thirty feet. The distinctively lobed trifoliate leaves are olive drab, and handsomely rustic.
