Culver's root Interesting Notes

With its candelabra-like display of white flowers, Culver’s root makes an elegant vertical statement in the mixed border or meadow planting. Occurring in early to mid-summer, white to pale lavender flowers are borne in dense arrangements on branched terminal spikes. Dark green leaves add visual interest with their whorled arrangement along the erect 3½-5’ stems. Plants flourish in full sun in an average to rich garden soil that is moist to wet and well drained. For an interplay of flower and foliage, pair with Andropogon virginicus, Rudbeckia maximaVernonia noveboracensis, and Echinacea purpurea 'Ruby Giant' in a naturalized setting. - Mt. Cuba Center
