Compare these two plants side by side — care needs, key differences, and which is right for your home.
Heliotrope
Heliotropium arborescens
Heliotropium arborescens, commonly known as Heliotrope, is a tender perennial shrub typically grown as an annual in cooler climates. It's prized for its intensely fragrant, vanilla-scented flowers, which are usually a deep purple or blue, though cultivars with white or pink flowers exist. The plant has a bushy growth habit and can reach a height of 1-4 feet. While it can be grown indoors, it requires very bright light and consistent care to thrive. People grow it for its beautiful, fragrant flowers that attract pollinators.
Pride of India
Lagerstroemia indica
Lagerstroemia indica, commonly known as Crape Myrtle or Crepe Myrtle, is a deciduous tree or large shrub prized for its vibrant summer flowers and attractive exfoliating bark. It typically grows to a height of 15-25 feet outdoors. The flowers come in a variety of colors, including pink, red, white, and lavender. While beautiful, it is primarily an outdoor plant and struggles to thrive indoors due to its high light and space requirements. People grow it for its ornamental value in gardens and landscapes.

❓ Frequently Asked Questions — Comparing These Plants
Heliotrope
What are the light requirements for Heliotrope?
Heliotrope flourishes in bright, indirect sunlight. While it can tolerate some direct morning sun, avoid harsh afternoon sun which can scorch the leaves. An east-facing window is often ideal. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides, preventing it from leaning excessively towards the light source. If natural light is limited, supplement with grow lights to provide the necessary intensity for healthy growth and abundant blooms. Observe the plant for signs of stress, such as pale leaves or stretched stems, which may indicate insufficient light.
How do I care for Heliotrope?
Heliotrope thrives in well-draining soil and requires regular watering, allowing the top inch of soil to dry out between waterings. Provide bright, indirect sunlight, preferably with some direct morning sun. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength to encourage blooming. Prune regularly to maintain shape and promote bushier growth. Deadhead spent flowers to encourage further blooming. Protect from frost as Heliotrope is sensitive to cold temperatures. Ensure good air circulation to prevent fungal diseases. Repot annually in spring to refresh the soil. Monitor for pests like aphids and spider mites and treat promptly. Maintain moderate humidity levels.
How do I propagate Heliotrope?
Heliotrope can be propagated through stem cuttings. Take 4-6 inch cuttings from healthy stems, removing the lower leaves. Dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting typically occurs in 4-6 weeks. Once rooted, transplant the cuttings into individual pots. Division is also possible with established plants, carefully separating the root ball in spring. While Heliotrope does not produce keikis, stem cuttings are the most effective propagation method. Ensure humidity is high during rooting.
Pride of India
What are the light requirements for Pride of India?
Pride of India requires bright, indirect light to thrive indoors. Insufficient light can lead to leggy growth, reduced flowering, and pale foliage. Place your plant near an east- or west-facing window where it can receive ample light without direct sun exposure. If you have a south-facing window, use sheer curtains to filter the sunlight. Rotate the plant regularly to ensure all sides receive adequate light. If natural light is limited, consider using a grow light to supplement its needs. A fluorescent or LED grow light positioned 12-18 inches above the plant can provide the necessary light for healthy growth and flowering.
How do I care for Pride of India?

Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and encourage bushier growth, removing any dead or crossing branches. Repot every 2-3 years into a slightly larger pot with well-draining potting mix. Maintain a stable temperature between 65-75°F (18-24°C). Monitor for pests like aphids or spider mites and treat promptly with insecticidal soap. Rotate the plant regularly to ensure even growth.
