True summer-flowering Clematis can be among the showiest of climbing perennials. Their inflorescences, sometimes fragrant, come laden with small to medium-sized flowers that range in color from white to a vast palette that includes yellow. Plants in this category are very diverse, bred from flammula, tangutica and viticella species, orientalis and climbing native North American viorna Clematis. A long blooming season, extended by trimming or even cutting the plants down hard, makes these attention-getting Clematis essential to garden displays.
Not all Clematis are pruned the same way--see our EZ Pruning Guide
