|A good cut flower, False Dragonhead blooms in late summer when other flowers do not. The buds on its branched spikes of flowers grow with geometrical precision on three sides of the stalk. The top of the stalk has tightly-closed buds, the lower buds slightly larger and the bottom ones fully open, funnel-shaped flowers. Use in moist borders and around ponds. If you twist the flowers on the stem, they stay in position, hence the second name, Obedience Plant. Thin frequently and prune spent flower stalks to encourage new ones. Sold in containers in the spring.
Spikes of white, rosy pink or lavender flowers rise above long, toothed, pointed leaves. Stake tall stems. Control by digging up spreading clumps and cutting to the ground after flowering.
