Clematis Plant. Clematis vines are climbers that can quickly cover a trellis or pergola in your garden. An important thing to note:
These plants like a lot of sun, but also prefer “cool roots” — tons of light directly on the base of the plants may stunt their growth. The goal is to plant it deep enough that the first set of leaves is kept on top of the soil surface. Clematis should be planted in the spring, to allow the plants to take hold before the harsh summer months.
