Common Name(s):Obedient Plant, False Dragonhead
Flowers: Pastel shades of white, pink & lavender. The flowers form along spikes, in four neat vertical rows, and begin opening from the bottom up.
Form: Although obedient plant can spread throughout the garden, the individual plants tend to be clumpers. The flower stalks will bend and stay bent if moved or blown over. Large plants may require staking and mature plants will thin out in the center and can take on an open, floppy form when it’s time to divide.
- Physostegia virginiana ' Miss Manners' - The name tells you this variety doesn’t spread. White flowers. 18-24".
- Physostegia virginiana 'Pink Bouquet' - Profuse bloomer. Soft pink flowers. Good choice for northern gardeners. 2-3'.
- Physostegia virginiana 'Summer Glow' - A tall grower with deeper lavender-pink flowers. 3-4'.
- Physostegia virginiana 'Variegata' - White edges on leaves make this variety interesting all season. Pink flowers. 18-24".
- Physostegia virginiana 'Vivid' - Forms short, dense clumps. Bright purple-pink flowers. 1-2'.
Propagating:Obedient plant can be started from seed, about 2 months before planting out, or divide existing clumps in the spring. Cuttings taken from young, tender shoots also root well.
Feeding:Don’t fertilizer your obedient plants, unless they show signs of nutrient deficiencies. Less fertilizer means less aggressive spreading.
Maintenance:The biggest maintenance chore is keeping obedient plant from rampant spreading. Although the plants pull out easily enough, they seem to pop up everywhere. If you’re tempted to wait and let them flower, be sure to get out there before they go to seed.
Long season gardeners can get a second flush of blooms if you deadhead the first flowers.
Wait until spring to cut back old foliage.
