False Dragonhead vs Nanking Cherry Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
False Dragonhead
Physostegia virginiana
Physostegia virginiana, commonly known as False Dragonhead or Obedience Plant, is a rhizomatous perennial herb typically found in moist meadows and along stream banks. It features upright, square stems and lance-shaped, toothed leaves. The plant produces dense spikes of tubular, two-lipped flowers in shades of pink, purple, or white during late summer and early fall. While admired for its late-season blooms and ease of cultivation, its aggressive spreading habit via rhizomes can make it challenging to manage in smaller gardens. It is primarily grown outdoors in gardens and naturalized areas.
Nanking Cherry
Prunus tomentosa
Nanking Cherry is a deciduous shrub typically growing to 8-10 feet tall and wide. It is known for its early spring display of fragrant, white to pink flowers that cover the branches before the leaves emerge. These flowers give way to bright red, edible cherries in early summer. While the fruit is edible, the pit contains cyanide compounds and should not be consumed. It is primarily grown as an ornamental shrub for its attractive flowers and fruit, and is sometimes used for hedging or as a wildlife plant.

❓ Frequently Asked Questions — Comparing These Plants
False Dragonhead
What are the light requirements for False Dragonhead?
False Dragonhead requires a minimum of six hours of direct sunlight daily for optimal growth and abundant flowering. A location with full sun is ideal, but it can tolerate partial shade, especially in hotter climates. In areas with intense afternoon sun, providing some afternoon shade can prevent leaf scorch. Insufficient light can lead to leggy growth, reduced flowering, and weaker stems. When planting, consider the amount of sunlight the area receives throughout the day. If growing indoors, place the plant near a sunny window, preferably south-facing. Rotate the plant regularly to ensure even light exposure on all sides. Supplemental lighting may be necessary during winter months or in areas with limited sunlight.
How do I care for False Dragonhead?
False Dragonhead thrives in full sun to partial shade, requiring at least 6 hours of sunlight daily for optimal blooming. Plant in well-draining soil that is consistently moist, but not waterlogged. Water deeply when the top inch of soil feels dry. Fertilize in spring with a balanced fertilizer to encourage healthy growth and abundant blooms. Deadhead spent flowers regularly to promote continuous blooming and prevent self-seeding, which can be aggressive in some cultivars. Divide clumps every 2-3 years in spring or fall to maintain vigor and prevent overcrowding. Provide support for taller varieties to prevent them from flopping over. Monitor for pests such as aphids and spider mites, and treat as needed. Prune back stems in late fall or early spring to prepare for the next growing season. Provide adequate air circulation to prevent fungal diseases. Amend heavy clay soils with organic matter to improve drainage.
How do I propagate False Dragonhead?
False Dragonhead can be easily propagated by division, stem cuttings, or seeds.
Nanking Cherry
What are the light requirements for Nanking Cherry?
Nanking Cherry trees thrive with ample light exposure. As an indoor tree, provide your Nanking Cherry with bright, indirect sunlight for at least 6 hours a day. An east- or west-facing window is ideal, as it offers sufficient light without direct sun exposure, which can scorch the leaves. If natural light is insufficient, supplement with a grow light to ensure healthy growth.
How do I care for Nanking Cherry?
Caring for a Nanking Cherry as an indoor tree requires attention to several key factors. Light is crucial; provide bright, indirect light, ideally near an east- or west-facing window. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix and a pot with drainage holes.
How do I propagate Nanking Cherry?
Nanking Cherry trees can be propagated through stem cuttings and air layering. For stem cuttings, take a 4-6 inch cutting from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist in a humid environment. Roots should develop in 4-6 weeks.
