Flame of the Woods vs Obedient Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Flame of the Woods
Ixora coccinea
Ixora coccinea, commonly known as Flame of the Woods, is a tropical evergreen shrub or small tree prized for its vibrant clusters of small, star-shaped flowers. The flowers typically come in shades of red, orange, yellow, or pink. It is a popular ornamental plant in warm climates, often used in hedges and foundation plantings. While it can be grown indoors, it requires very specific conditions and is more commonly cultivated outdoors. People grow it for its showy blooms and dense foliage, adding a splash of color to landscapes.
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
Flame of the Woods
What are the light requirements for Flame of the Woods?
Flame of the Woods requires bright, indirect light to thrive and produce abundant blooms. Insufficient light can result in leggy growth and a lack of flowering. A location near an east-facing or west-facing window is ideal, providing ample light without the harshness of direct sunlight. If placed near a south-facing window, use sheer curtains to filter the light. Rotate the plant regularly to ensure even light exposure on all sides. During the winter months, when light levels are lower, consider supplementing with a grow light to maintain adequate illumination. Avoid placing the plant in deep shade, as this will significantly hinder its growth and flowering potential. The plant’s leaves should be a healthy green color; pale or yellowing leaves may indicate insufficient light.
How do I care for Flame of the Woods?
Flame of the Woods thrives with bright, indirect light; direct sunlight can scorch its leaves. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain high humidity levels by misting regularly or using a humidifier, especially in drier climates. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer formulated for flowering plants. Reduce fertilizing in fall and winter. Prune after flowering to maintain shape and encourage bushier growth. Repot every 1-2 years in spring, using a well-draining potting mix. Keep the plant in temperatures between 65-80°F (18-27°C). Avoid exposing it to temperatures below 60°F (15°C). Check regularly for pests like spider mites and mealybugs, and treat promptly if found. Ensure good air circulation to prevent fungal diseases. Provide a slightly acidic soil pH for optimal growth.
How do I propagate Flame of the Woods?
Flame of the Woods can be propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide high humidity by covering the cutting with a plastic bag or dome. Place in bright, indirect light. Roots should develop in 4-6 weeks. Division is possible, but less common. Keiki propagation is not applicable to this species. Ensure the parent plant is healthy before taking cuttings. Maintain a warm environment for successful rooting.
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.
