Exacum vs Sago Palm 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.
Sago Palm
Cycas revoluta
Despite its common name, the Sago Palm is not a true palm but a cycad, an ancient group of plants that predate flowering plants. It features a stout, palm-like trunk and a crown of stiff, feathery, dark green leaves. It is a slow-growing plant, typically grown as an ornamental plant in gardens and containers. While it can be grown indoors, it requires very bright light and is more commonly found outdoors in warmer climates. People grow it for its tropical appearance and architectural form.

❓ 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.
Sago Palm
What are the light requirements for Sago Palm?
Sago Palms require bright, indirect light to thrive. They can tolerate some direct sunlight, especially in the morning or late afternoon, but prolonged exposure to intense midday sun can scorch their fronds. An east- or west-facing window is ideal, providing ample light without the harshness of direct sun. If growing indoors, rotate the plant regularly to ensure even growth. If the leaves start to yellow or become pale, it may indicate insufficient light. Conversely, brown, crispy tips suggest too much direct sun. Supplement with a grow light if natural light is limited, especially during winter months.
How do I care for Sago Palm?
Sago Palms thrive in bright, indirect light and well-draining soil. Water thoroughly when the top inch of soil is dry, allowing excess water to drain away. Avoid overwatering, as this can lead to root rot. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Maintain moderate humidity levels. Repot only when the plant becomes root-bound, typically every few years. Prune dead or yellowing fronds at the base. Protect from frost and extreme cold. Ensure good air circulation to prevent fungal diseases. Wipe leaves occasionally to remove dust and improve light absorption. Sago Palms are slow-growing and require minimal maintenance once established. Always handle with care, as the leaves have sharp points.
How do I propagate Sago Palm?
Sago Palms can be propagated from seeds or by removing offsets (pups) that grow at the base of the plant. Seed propagation is slow and can take several months to years for germination. To propagate from offsets, carefully detach the pup from the main trunk, ensuring it has some roots. Allow the cut end to callous over for a few days before planting in well-draining soil. Keep the soil consistently moist but not waterlogged. Place the pup in a warm, bright location with indirect light. Rooting can take several weeks to months. Be patient and avoid disturbing the pup during this time. Division is best done in spring or early summer.
