Scientific Synonyms:

Dracocephalum virginianum

Description

Phobedient plantysostegia virginianais a very attractive member of the Mint family. The stems are typically square, can grow up to 4' tall, and are topped with spikes of large, pinkish, tubular, snapdragon-like flowers. The leaves are elongated, lance-shaped, and about 4" long.

Cultivation

Obedient plant is very easy to grow and highly adaptable. Its form will vary depending on growing conditions; a dryer, poorer environment will yield shorter but sturdier plants, while a richer environment will produce taller but weaker stems that might require staking. Pinching the stems early in their growth will produce bushier plants and increase the number of flowering branches. It is tolerant of dry soils in shaded locations, and of saturated poorly-drained soils in full sun. As with many other members of the Mint family, it can spread rather aggressively by both rhizomes and from seed, forming large dense colonies. The plants are shallow-rooted and easy to pull if a more controlled spread is desired. Divide clumps every 2 to 3 years to maintain healthy populations. Plants will flower for several months. Due to its broad geographic distribution, actual bloom times are difficult to pinpoint, but will usually be from June to October. Zones 3-9

Propagation

Very easy to propagate from seed, or by division in early spring. Young stem cuttings can also be rooted.

Additional Notes

Physostegia virginiana produces long lasting cut flowers. Individual blossoms can be bent and will hold their new position. This particularity gave rise to the common name "obedient plant". This is a very showy plant that will provide visual interest late in the season. A good choice for cottage gardens and perennial flower borders. It is also a good choice for naturalized ares, where it will hold its own against most grasses...and against deer!
