Summary
Beautiful upright spikes of snapdragon-like flowers are borne abundantly atop obedient-plant (Physostegia virginiana) in summer. Easy to grow, this robust herbaceous perennial is best suited for full sun to partial shade in moist to dry soils, and plants perform well in less fertile soils. Lavender to white tubular blooms on square stems are ‘obedient’, when moved, remaining in any new position as if wired in place. Obedient-plant spreads both by prolific seeds and rhizomatous growth. Any border or naturalized area will be brightened when obedient-plant is planted alongside goldenrods (Solidago spp.), clasping aster (Symphyotrichum patens), stiff-leaved aster (Ionactis linariifolius), scarlet bee balm (Monarda didyma), little bluestem (Schizachyrium scoparium), and purple coneflower (Echinacea purpurea). Zones 3-9.
