Growing Obedient Plant (Physostegia) with Spread Control

Pronunciation: fie-so-stee'gee-uh

Full sun or partial shade. Best in average to damp soil. Can be invasive, especially in moist conditions—lift and divide every 2–3 years to contain it. (P. virginiana 'Variegata' is less vigorous and less likely to spread.) If plants flop, pinch back by half in late spring to keep compact.
