What Is Japanese Aralia?

Table of Contents

Japanese Aralia, or Fatsia Japonica, is an evergreen shrub native to Japan and Korea. It belongs to the ivy family, Araliaceae, and is closely related to other popular houseplants like false aralia and umbrella tree. This plant is known for its striking, palmate leaves that are deeply lobed and can grow up to eight inches wide or larger. When grown indoors, Japanese Aralia typically reaches a height of around six feet.

In addition to its beautiful foliage, Japanese Aralia produces fragrant white blooms in the fall, followed by dark blue berries that add a unique touch to its appearance. The plant is a versatile addition to any indoor space, thanks to its adaptability to different light conditions and its tolerance for low light environments.

Cultivation and History

Fatsia Japonica has a rich history dating back to the 19th century when it was taxonomically categorized. In its native regions of Japan and Korea, the plant is not only admired for its beauty but also valued for its edible sprouts, which are considered a delicacy.

Japanese Aralia can be grown both indoors and outdoors, with outdoor cultivation possible in USDA Hardiness Zones 7b to 10b. The plant’s cold tolerance makes it a popular choice for ornamental gardens and landscaping.

Propagation

Japanese Aralia can be propagated from seeds, cuttings, or transplants. If you’re looking to propagate a specific cultivar, such as ‘Spider’s Web’ or ‘Annelise,’ cuttings are the preferred method since seeds from cultivated varieties may not grow true.

From Seed: Growing Japanese Aralia from seed is a straightforward and cost-effective option. Start by collecting mature seeds from the plant’s berries and follow germination methods such as moist paper towels or direct sowing in nursery pots.
From Cuttings: Propagating Japanese Aralia from cuttings is ideal for cultivating specific cultivars or maintaining the characteristics of the parent plant. Take semi-ripe cuttings in late summer to mid-autumn, root them in water or growing medium, and transplant once roots have developed.
From Transplants: When transplanting a new specimen, assess whether it requires immediate repotting based on its growth and condition. Choose a pot with adequate drainage and a well-draining growing medium to ensure healthy plant growth.

How to Grow Japanese Aralia

To ensure the optimal growth and health of your Japanese Aralia, it’s essential to consider its light, water, soil, and climatic requirements. Here are some key tips for successfully growing Fatsia Japonica indoors:

Light: Japanese Aralia thrives in indirect bright, medium, or low light conditions. Avoid direct sunlight, as it can scorch the plant’s leaves.
Water: Keep the plant’s soil moist but not soggy, and avoid letting it dry out completely. Japanese Aralia will wilt dramatically when thirsty, so monitor soil moisture levels regularly.
Soil: Use a well-draining, slightly acidic growing medium with a pH range of 5.5 to 6.0. Rich in organic matter, the soil should provide ample aeration for healthy root development.
Temperature: Maintain a temperature range of 60 to 80°F during the summer months and 45 to 55°F in the winter. Protect the plant from extreme cold temperatures below 10°F.
Humidity: Japanese Aralia prefers a humidity level of 60% or higher. In low humidity environments, consider using a humidifier to create an optimal growing environment.

Pruning and Maintenance

Regular pruning and maintenance are essential for keeping your Japanese Aralia healthy and vibrant. When repotting the plant, choose a pot that is one size larger than the current container and ensure it has proper drainage. Monitor the plant for signs of overgrowth, wilting, or pest infestations, and address any issues promptly.

To maintain the plant’s shape and vigor, prune back one third of the foliage at a time, using sterilized tools to prevent disease spread. Fertilize Japanese Aralia with a balanced, gentle fertilizer during the growing season to provide essential nutrients for healthy growth.

Hybrids and Cultivars to Select

When selecting a Japanese Aralia cultivar, you have a variety of options to choose from, each with unique characteristics and visual appeal. Popular cultivars like ‘Annelise,’ ‘Annemieke,’ and ‘Spider’s Web’ offer distinct foliage patterns and color variations that can enhance your indoor space. Consider these cultivars when looking to add a touch of sophistication to your plant collection.

Managing Pests and Diseases

Like many houseplants, Japanese Aralia is susceptible to common pests and diseases that can affect its health and appearance. Keep an eye out for aphids, mealybugs, scale, and spider mites, which can feed on the plant’s nutrients and weaken its vitality. Regularly inspect your Japanese Aralia for signs of infestations and treat them promptly using safe and effective methods such as neem oil.

Preventative measures such as proper watering, well-draining soil, and adequate humidity levels can help reduce the risk of root rot, a common issue that can impact the plant’s root system. By maintaining a healthy growing environment and practicing good plant care habits, you can minimize the risk of pests and diseases affecting your Japanese Aralia.
