Obedient Plant Physostegia virginiana var. speciosa 'Variegata' (v)
ABOUT
Commonly known as the variegated obedient plant, the main characteristic that sets this variety apart is its foliage, which usually shows a striking variegation pattern. The leaves are typically green with creamy-white to pale yellow margins, adding a decorative contrast against the lush green backdrop of a garden. The leaves are lance-shaped and can exhibit a slightly toothed edge, which adds texture to its appearance. This plant is adorned with spike-like flower stems that bear a series of tubular flowers. The flowers themselves come in shades of pink to lavender, arranged in a tight, stacked fashion along the stem. The individual blossoms can resemble snapdragons in shape, featuring a hooded upper lip and a wider lower lip. The variegated patterning of the leaves paired with the soft hues of the flowers make this plant a standout in any garden setting. The contrast between the foliage and blooms creates a striking visual that can draw the eye and serves as a point of interest throughout its blooming period.

WaterObedient Plant prefers consistent moisture, but it is also important to avoid overwatering. It should be watered deeply once a week, ensuring that the soil is moist but not soggy. During hot and dry periods, the watering frequency should increase to twice a week. A good rule of thumb is to provide the Obedient Plant with about 1 inch of water per week, whether from rainfall or manual watering. For a more specific measurement, this translates to about 0.623 gallons per square foot every week.
LightThe Obedient Plant thrives best in full sun to partial shade. It should be placed in a location where it can receive at least six hours of direct sunlight per day. If grown indoors, a bright, south-facing window is ideal to provide the required light conditions.
TemperatureObedient Plants are hardy and can tolerate a range of temperatures but perform best when the temperature is between 60°F and 75°F. They can endure minimum temperatures down to about 40°F and maximum temperatures up to around 90°F, but extended periods outside this range may compromise their health and blooming capability.
PruningTo encourage bushier growth and more abundant blooming, the Obedient Plant should be pruned in the early spring or after the first flush of flowers fade. Deadheading spent blooms can promote a second bloom period in the fall. Pruning is typically done once a year, but spent flowers can be removed as needed throughout the growing season.
CleaningAs needed
SoilObedient plant 'Variegata' thrives in moist, well-draining soil with a pH ranging from 6.0 to 7.0. A mix of garden soil, compost, and a bit of sand or perlite is ideal to ensure proper drainage and fertility. This variegated variety benefits from a soil that can retain moisture without becoming waterlogged, so a balanced loamy mixture is perfect.
RepottingObedient plant 'Variegata' generally does not require frequent repotting, as it is a herbaceous perennial that spreads through rhizomes. Repot or divide it every 3-4 years to rejuvenate the soil and manage the spread of the plant or when you see signs of overcrowding in its current container.
Humidity & MistingObedient plant 'Variegata' is adaptable to a wide range of humidity levels but prefers average ambient humidity found in most outdoor garden settings. It does not require any special humidity considerations when grown in its ideal outdoor environment.

Life cycleVariegated Obedient Plant (Physostegia virginiana var. speciosa 'Variegata') begins its life cycle as a seed that germinates in late winter to early spring. The seedlings develop into rosettes of variegated foliage, which elongate into erect stems as temperatures warm. Throughout summer, the plant grows vigorously, producing distinctive square stems typical of the mint family, with leaves boasting creamy-white margins. By late summer to early fall, it reaches full maturity with spikes of tubular, pink to lavender flowers that attract pollinators like bees and butterflies. After flowering, the plant sets seed, which can be dispersed for reproduction. As winter approaches, the aerial parts of the plant die back to the ground, and it overwinters as underground rhizomes, ready to sprout again the following spring.

Spring to Summer
The most popular method of propagation for the Obedient Plant, Physostegia virginiana var. speciosa 'Variegata', is by division. This is best done in the spring as new growth appears. Gardeners should carefully dig up the plant, making sure to get as much of the root system as possible. Then, using a sharp knife or spade, they can divide the root clump into smaller sections, ensuring that each section has at least one growth point or bud. These individual sections can then be replanted in well-prepared soil, spaced about 18 to 24 inches apart, which equates to approximately 45 to 60 centimeters. Water the new divisions well and maintain even moisture until they show signs of new growth and are well established.
