Rainy Side Notes

Clematis integrifolia was first introduced to Britain in 1597. A cottage garden staple, this species only grows a few feet tall and doesn't climb like most of its relatives in the genus. It is one of the few clematis that you can divide like a perennial and grow out in the middle of the border without something to climb on. You can stake this species to stand upright, or let it flop on the ground or interweave itself amongst other perennials or shrubs.

This herbaceous perennial or subshrub is a parent to many interesting hybrids, such as C. x durandii, which is a cross between C. integrifolia and the popular C. 'Jackmanii'.
