Myoporum vs Obedient Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Myoporum
Myoporum parvifolium
Myoporum parvifolium is a fast-growing, prostrate groundcover native to Australia. It features small, succulent-like leaves that are typically bright green but can exhibit reddish hues in cooler months. It spreads quickly, forming a dense mat that suppresses weeds. While it can be grown in containers, it's primarily used as an outdoor groundcover due to its spreading habit and need for ample sunlight. People grow it for its drought tolerance, erosion control capabilities, and attractive foliage.
Obedient Plant
Physostegia virginiana
Physostegia virginiana, commonly known as Obedient Plant, is a herbaceous perennial native to North America. It's characterized by its upright growth habit and lance-shaped, toothed leaves. The plant produces spikes of tubular flowers in shades of pink, lavender, or white during late summer and early fall. It gets its name from the fact that if you gently bend the flowers on the stem, they will stay in the position you put them, hence 'obedient'. Primarily an outdoor plant, it's grown in gardens for its late-season blooms and attractiveness to pollinators. Indoor cultivation is challenging due to its high light and space requirements.

❓ Frequently Asked Questions — Comparing These Plants
Myoporum
What are the light requirements for Myoporum?
Myoporum requires bright, indirect light to thrive indoors. Insufficient light can lead to leggy growth and reduced foliage density. A location near an east- or west-facing window is ideal, providing ample sunlight without direct, scorching rays. If direct sunlight is unavoidable, filter it with sheer curtains.
How do I care for Myoporum?
Myoporum thrives indoors with bright, indirect light. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Use a well-draining potting mix and a pot appropriate for its size. Maintain a stable temperature between 60-75°F (15-24°C). Prune regularly to maintain shape and encourage bushier growth. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Myoporum?
Myoporum can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. 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. Roots should develop in 4-6 weeks.
Obedient Plant
What are the light requirements for Obedient Plant?
Obedient Plant thrives best in full sun, requiring at least 6 hours of direct sunlight per day to produce abundant blooms and maintain strong, upright growth. In hotter climates, some afternoon shade can be beneficial to prevent leaf scorch. Insufficient sunlight can lead to leggy growth, reduced flowering, and weaker stems. When grown indoors, place Obedient Plant near a sunny window, such as a south-facing or west-facing exposure. 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 natural light.
How do I care for Obedient Plant?
Obedient Plant thrives in full sun to partial shade and prefers moist, well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further blooming. Be aware that Obedient Plant can be aggressive; consider planting it in containers or using barriers to control its spread. Prune back stems after flowering to maintain shape and prevent excessive self-seeding. Monitor for pests like aphids and spider mites, and treat as needed. Provide adequate air circulation to prevent fungal diseases.
How do I propagate Obedient Plant?
Obedient Plant can be easily propagated through division, stem cuttings, or seeds. Division is best done in early spring or fall by separating the rhizomes and replanting them. For stem cuttings, take 4-6 inch cuttings from healthy stems in late spring or early summer. Remove the lower leaves and plant the cuttings in moist potting mix. Keep the cuttings humid by covering them with a plastic bag or dome. Seeds can be sown directly in the garden in fall or started indoors in early spring. Keep the soil moist until germination.
