Clematis is one of the most popular flowering vines. They bloom in almost every colour; flowers can be single or double ranging from small to large. Their shape can be tubular, star-like, flat open discs or nodding bells.
Depending on the cultivar, flowering can take place in spring and again in late summer, all summer, or in late summer through fall. Given proper support, they are easy to grow. Clematis climbs by twining slender stems (petioles) around a wire (non-rusting, either galvanized or plastic coated) or other thin supports.
They can be grown on a wall, fence, pergola, trellis, arbour, obelisk, or pole. They can also be trained to grow on trees, conifers, shrubs, or with climbing roses.
