Exacum vs Piggyback Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Exacum
Exacum affine
Exacum affine, commonly known as Persian Violet, is a small, bushy, herbaceous perennial often grown as an annual. It typically reaches a height of 15-30 cm. It features small, oval, glossy green leaves and a profusion of fragrant, star-shaped flowers, usually violet-blue, but also available in white, pink, and lavender. While technically a perennial, it is most often cultivated as an annual or a houseplant due to its sensitivity to cold temperatures. People grow it for its charming, long-lasting blooms and sweet fragrance.
Piggyback Plant
Tolmiea menziesii
Tolmiea menziesii, commonly known as the Piggyback Plant, is a perennial herbaceous plant prized for its unique propagation method. Small plantlets develop on the upper surface of its mature leaves, giving the appearance of a 'piggyback' ride. These plantlets can then be detached and planted to create new individuals. It is naturally found in moist, shaded forests and along stream banks. While it can be grown indoors, it thrives best with consistent moisture and cooler temperatures, mimicking its native habitat. People grow it for its unusual appearance and ease of propagation.

❓ Frequently Asked Questions — Comparing These Plants
Exacum
What are the light requirements for Exacum?
Exacum thrives in bright, indirect light. An east-facing window is ideal, providing gentle morning sun. Avoid direct sunlight, especially during the hottest part of the day, as it can burn the delicate leaves and fade the flowers. If you don’t have access to a bright window, consider using a grow light to supplement the natural light. Rotate the plant regularly to ensure even growth and blooming on all sides. Insufficient light can result in leggy growth and reduced flowering. If the leaves start to turn pale or yellow, it may be a sign of too much direct light.
How do I care for Exacum?
Exacum prefers bright, indirect light; direct sunlight can scorch the leaves. Water when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity, ideally between 50-60%. Fertilize every 2-4 weeks during the blooming season with a balanced liquid fertilizer diluted to half strength. Keep temperatures between 60-75°F (15-24°C). Prune spent flowers to encourage continuous blooming. Repot only when necessary, using a well-draining potting mix. Avoid overwatering and provide good air circulation. Monitor for pests such as aphids or spider mites and treat promptly. Deadhead regularly. Provide a consistent environment to avoid stress. Ensure adequate drainage to prevent soggy soil.
How do I propagate Exacum?
Exacum can be propagated from stem cuttings. Take a 2-3 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 bright, indirect light. Cover with a plastic bag to increase humidity. Roots should develop within a few weeks. Once rooted, transplant into a larger pot. Exacum is not typically propagated by division or keiki. Ensure the cutting is free from disease or pests. Mist regularly to maintain humidity during rooting. Provide bottom heat to encourage faster root development.
Piggyback Plant
What are the light requirements for Piggyback Plant?
Piggyback Plants thrive in bright, indirect light. Direct sunlight can scorch their delicate leaves, so avoid placing them in south-facing windows unless the light is filtered. An east- or north-facing window is generally ideal, providing ample light without the harshness of direct sun. If you notice the leaves becoming pale or leggy, it may indicate insufficient light.
How do I care for Piggyback Plant?
