Physostegia virginiana 'Crown of Snow' (Obedient Plant) is an upright herbaceous perennial boasting dense spikes of snow-white tubular flowers from mid-late summer to fall. Blooming from the bottom to the top on each spike, the showy blossoms are attentively visited by hummingbirds and butterflies. They rise on stiff, square stems clad with narrow, lance-shaped leaves. Great for sunny prairies and meadows. Excellent cut flowers.

• Grows up to 36 in. tall (90 cm) and 12-18 in. wide (30-45 cm). May grow aggressively in moist rich soil and form spectacular colonies.
• Easily grown in fertile, moist, well-drained soils in full sun. Tolerates wet soils and some part shade (plant will flop in too much shade). Plants are not fussy as to soil but perform better in acid pH.
• Great for beds and borders, cottage gardens, rain gardens or prairies.
• Virtually disease and pest free. Keep an eye out for aphids and spider mites.
• Cut back to the base in winter
• Propagate by division in winter or early spring before new growth starts.
