Japanese Aralia

Fatsia japonica

Fatsia japonica, or Japanese Aralia, is an evergreen shrub or small tree known for its large, palmate (hand-shaped) leaves. It typically grows to 1-3 meters tall indoors, though can reach greater heights outdoors. The leaves are glossy, deeply lobed, and can be up to 30-50 cm across. While it can be grown indoors, it thrives outdoors in temperate climates. People grow it for its bold foliage and architectural presence, adding a tropical or exotic touch to gardens and interiors. Indoor cultivation can be challenging due to its need for bright light and cool temperatures.

❓ Frequently Asked Questions — Comparing These Plants

Greater Celandine

What are the light requirements for Greater Celandine?

Greater Celandine prefers partial shade to full shade, thriving in locations that receive dappled sunlight or filtered light throughout the day. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. An east-facing location or a spot under a tree canopy is ideal. Insufficient light can result in leggy growth and reduced flowering. If growing indoors, place the plant near a north-facing window or provide artificial light with a grow light for several hours per day. Monitor the plant for signs of stress, such as pale leaves or sunburn, and adjust the light accordingly.

How do I care for Greater Celandine?

Greater Celandine thrives in partial shade to full shade and prefers moist, well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize sparingly with a balanced liquid fertilizer diluted to half strength, only during the growing season (spring and summer) to encourage blooming. Deadhead spent flowers to promote further blooming and prevent excessive self-seeding. Monitor for pests such as aphids and slugs, and treat accordingly. Prune back any dead or damaged foliage to maintain plant health and appearance. Provide adequate air circulation to prevent fungal diseases. Mulch around the base of the plant to retain moisture and suppress weeds. Repotting is rarely necessary as Greater Celandine prefers to be slightly root-bound.

How do I propagate Greater Celandine?

Greater Celandine can be propagated through division. In early spring or fall, carefully dig up the plant and gently separate the roots into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Keep the soil consistently moist until new growth appears. Stem cuttings are not a reliable method for propagation. Greater Celandine does not produce keikis. Division is the most effective and straightforward way to propagate this plant, allowing you to expand your collection or share it with others. Ensure the divisions are planted in a location with similar light and soil conditions as the parent plant.

Japanese Aralia

What are the light requirements for Japanese Aralia?

Japanese Aralia thrives in bright, indirect light. Direct sunlight can burn its delicate leaves, so avoid placing it in a south-facing window without any protection. An east or west-facing window is ideal, where it will receive gentle morning or afternoon light. If your space lacks sufficient natural light, consider supplementing with a grow light. Rotate the plant regularly to ensure even growth on all sides. Insufficient light can lead to leggy growth and pale leaves.

How do I care for Japanese Aralia?

To care for your Japanese Aralia, provide bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring proper drainage. Reduce watering in winter. Maintain moderate humidity levels. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years, or when the plant becomes root-bound, using a well-draining potting mix. Prune to maintain shape and remove any dead or damaged leaves. Keep temperatures between 60-75°F (15-24°C). Regularly check for pests and address any infestations promptly.

How do I propagate Japanese Aralia?

Japanese Aralia can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. 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 increase humidity. For air layering, make a small cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots develop, cut the stem below the roots and plant it in a pot. Both methods are best done in spring or early summer.
