Habit: This is an herbaceous plant that reaches about three to four feet tall and slightly less wide in one growing season, before the stems die back in the fall.

How to grow it: Site this clematis in full sun or light shade. Like other clematis, it grows best with its base shaded and the roots mulched well. Plant it slightly lower than it was growing in its nursery pot, even burying the bottommost leaves. This is a “Group 3” clematis, important to know for pruning purposes. Group 3 clematis bloom on the new growth of the year, which begins in spring from below the ground. Old stems should be cut back to about four inches above the soil in late winter. Although 'Stand By Me Lavender' is a bush clematis, and technically not a climber, it does look best with the support of a cage or tuteur. USDA Zones 3–7.
