False Dragonhead vs Lovage 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.
Lovage
Levisticum officinale
Lovage is a tall, herbaceous perennial plant typically grown outdoors for its leaves, stems, and roots, all of which have a celery-like flavor. It can reach heights of 1.8 to 2.5 meters (6 to 8 feet). The plant features glossy, dark green leaves that are divided into leaflets. It produces umbels of yellowish-green flowers in the summer, followed by aromatic seeds. People grow lovage for culinary and medicinal purposes. It is primarily an outdoor plant and presents challenges when grown indoors due to its size and light requirements.

❓ 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.
Lovage
What are the light requirements for Lovage?
Lovage performs best in full sun to partial shade. Ideally, it should receive at least six hours of direct sunlight per day to promote vigorous growth and abundant blooms. In hotter climates, afternoon shade is beneficial to prevent leaf scorch. When grown indoors, place Lovage near a sunny window, such as a south- or west-facing window. If natural light is insufficient, supplement with grow lights to ensure adequate light exposure. Rotate the plant regularly to ensure even light distribution and prevent it from leaning towards the light source. Insufficient light can lead to leggy growth and reduced flowering.
How do I care for Lovage?
Lovage thrives in well-drained soil and prefers a sunny to partially shaded location. Water deeply and regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further blooming and prevent self-seeding, unless you desire new plants. Prune back the plant in late fall after the foliage has died back to prepare it for winter dormancy. Provide support if the plant becomes too tall or top-heavy, especially in windy areas. Monitor for pests and diseases, and address any issues promptly. Mulch around the base of the plant to retain moisture and suppress weeds.
How do I propagate Lovage?
Lovage can be propagated through several methods: division, stem cuttings, and seed. Division is best done in spring or fall. Carefully dig up the plant and divide the root ball into smaller sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-draining soil. Stem cuttings can be taken in spring or summer. Take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and plant in a well-draining potting mix. Keep the soil moist until roots develop. Seeds can be sown directly into the garden in spring or fall. Keep the soil moist and provide adequate light. Germination can take several weeks.
