Exacum vs Ginkgo 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.
Ginkgo
Ginkgo biloba
Ginkgo biloba, the Maidenhair Tree, is a unique species of tree with no close living relatives. It's characterized by its fan-shaped leaves that turn a vibrant golden yellow in the fall. Ginkgos are dioecious, meaning there are separate male and female trees. Female trees produce seeds with a fleshy outer layer that has a very unpleasant odor when ripe. Ginkgos are incredibly hardy and long-lived, often planted as ornamental trees in parks and gardens. They are deciduous and lose their leaves in the winter. Ginkgos are not suitable for indoor growing due to their size and high light requirements.

💡 Pro Tips For Comparing These Plants
Exacum Care Tips
Exacum affine requires bright, indirect light, consistent moisture, and moderate humidity. It is sensitive to overwatering and cold drafts. Maintaining proper humidity is crucial for preventing bud drop. It is toxic to pets, so keep it out of reach.
- Use a well-draining potting mix to prevent root rot.
- Maintain moderate humidity by misting regularly or using a humidifier.
- Avoid placing the plant in direct sunlight, which can scorch the leaves.
- Pinch back stems to encourage bushier growth and more blooms.
- Fertilize regularly during the growing season to promote flowering.
Ginkgo Care Tips
Ginkgo biloba is not suitable for indoor growing. It requires full sun, ample space, and specific temperature fluctuations to thrive. It's a large outdoor tree that is relatively low-maintenance once established, but requires careful consideration of location due to its potential size and the unpleasant odor of the fruit from female trees.
- Choose a male tree to avoid the unpleasant odor of the fruit from female trees.
- Ensure well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
- Protect young trees from strong winds.
- Fertilize in early spring with a balanced fertilizer.

❓ 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.
Ginkgo
What are the light requirements for Ginkgo?
Ginkgo trees thrive in bright, indirect light. Too little light can lead to leggy growth and pale leaves, while direct sun can cause scorching. An east-facing window is ideal, providing gentle morning sun. A south- or west-facing window can also work, but filter the light with a sheer curtain to prevent leaf damage. If natural light is insufficient, supplement with a grow light. Rotate your Ginkgo regularly to ensure all sides receive adequate light, promoting even growth and preventing it from leaning towards the light source. Monitor the leaves for signs of overexposure (scorching) or underexposure (paleness).
How do I care for Ginkgo?
Indoor Ginkgo trees require bright, indirect light; direct sunlight can scorch their leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Maintain moderate humidity levels. Prune lightly to shape the tree and remove any dead or damaged branches. Repot every few years as needed, choosing a pot only slightly larger than the previous one. Protect from extreme temperature fluctuations and drafts. Regularly check for pests and address promptly. Provide consistent care to ensure healthy growth and vibrant foliage. Rotate the plant regularly to ensure even growth on all sides.
How do I propagate Ginkgo?
Ginkgo can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in the spring. 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. Cover with a plastic bag to maintain humidity. Rooting can take several weeks. For air layering, make a shallow cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Once roots develop, cut the stem below the roots and plant it in a pot. Both methods require patience and consistent care. Ensure adequate humidity and warmth for successful propagation.
