Clematis

Clematis is a genus of roughly 380 species, mostly known as beautiful climbing vines, though some grow as herbaceous perennials or shrubs. The physical characteristics vary greatly between species; however, they generally feature woody, twining stems and often grow quite tall, sometimes over 30 feet, wrapping their leaf stalks around supports to climb. The leaves are usually oppositely arranged and can be simple or compound, typically being non-toxic but not safe for ingestion either. The flowers are the main attraction for gardeners; they are showy and diverse, coming in a kaleidoscope of colors like blue, purple, red, pink, and white, with shapes ranging from star-like and bell-shaped to frilly doubles.
