About Clematis

Showy flowers in a range of colors and shapes. Best in full sun (unless noted otherwise), with roots protected from the hottest midday rays. Climbs by twining leaves that must grab something less than a half-inch in diameter. All clematis are toxic to people and pets. Deer- and rabbit-resistant. Great scrambling through shrubs or other supports, or even as a ground cover. For a note on pruning groups, see https://www.friendsschoolplantsale.com/clematis.
