Physostegia virginiana 'Summer Snow'

Obedient Plant (Physostegia virginiana 'Summer Snow') is an erect, hardy clump-forming perennial with long spikes of soft, white, tubular flowers in summer. The flowers are attractively blushed with pink and are arranged in succession along the stem. The lance-shaped leaves are green and grow up to 5 inches in length. The odorless flowers will continuously face to the same direction when touched, thus giving rise to its name. Obedient Plant is great for adding texture and height to garden borders or as a cut flower. It is hardy and requires full sun and moist, well-drained soil. It also has good resistance to deer.

watering

The obedient plant (Physostegia virginiana 'Summer Snow') should be watered thoroughly but infrequently. During the summer months, water the plant once a week. Make sure to water the soil deeply and not just lightly sprinkle the top of the soil. During the winter months, allow the soil to dry out completely between waterings. Additionally, make sure the obedient plant is located in an area with good drainage. Standing water and soggy soil can cause the roots to rot.

sunlight

Obedient plant (Physostegia virginiana 'Summer Snow') requires full sun to partial shade. During the spring and summer it needs at least 6 hours of direct sunlight per day. The sunlight should be from midmorning to late afternoon. During the fall and winter it should have filtered sunlight or partial shade. If the plant is given too much direct sunlight in the winter months it could suffer from sunburn.

pruning

Obedient Plant can be pruned twice a year for a neat, attractive look. Prune in late winter/early spring before new growth emerges, then again in late summer just before it begins to flower. Remove individual stems by cutting them off at the base or stem for a bushy, fuller growth. Remove any dead or damaged stems and cut off any flowered stems as they fade. Be careful not to over prune the stems, as this can damage the plant and reduce growth. Additionally, a light trim of the tallest stems can be done in late summer or early fall in order to reduce height.
