Plant Description

Japanese Aralia, botanically known as Fatsia japonica, is an eye-catching evergreen shrub. Its origin traces back to the subtropical regions of Japan, South Korea, and Taiwan. Due to its striking aesthetics and adaptability to indoor conditions, it has gained popularity worldwide as an indoor plant.

This plant is distinguished by its large, glossy, and deeply lobed leaves that fan out, making it a striking addition to any interior. On mature plants, these leaves can reach up to 16 inches in diameter, giving the plant an impressive visual appeal. Interestingly, ‘Fatsia’ is an approximation of the old Japanese word for ‘eight,’ referring to the eight lobes of the leaf.

Japanese Aralia blooms in the late fall to early winter, producing small, creamy-white flowers grouped in showy, spherical clusters, which then turn into black, ornamental berries. This blooming process adds an additional level of beauty to this already appealing plant.

Japanese Aralia

In its natural habitat, Japanese Aralia can grow up to 15 feet tall. However, when grown indoors, it usually reaches a manageable size of 5 to 8 feet. This plant can thrive in USDA hardiness zones 8 through 11, making it versatile for a variety of climates.

Japanese Aralia favors a shady location, mimicking its natural habitat under the forest canopy. This adaptability to lower light conditions makes it an ideal plant for indoor settings or darker corners of your garden. It prefers well-drained, fertile soil with a slightly acidic to neutral pH.

Being an evergreen, Japanese Aralia keeps its lush, deep green leaves throughout the year, making it a reliable source of vibrant greenery in your indoor or outdoor spaces. Its resilience and robustness, combined with its stunning aesthetics, make Japanese Aralia an excellent choice for anyone looking to add a touch of nature to their surroundings.


Identification of Plant

Japanese Aralia is a remarkable plant to identify, thanks to its unique appearance. It has large, glossy, deep green leaves that are deeply lobed, often resembling the shape of a hand with open fingers. These leaves can reach up to 16 inches in diameter on mature plants, giving the plant a dense, bushy appearance.

Its branches arch upwards, and the leaves cluster at their ends, providing an umbrella-like cover. The stems are thick and woody, making them sturdy enough to support the weight of the large leaves.

Japanese Aralia blooms from late fall into early winter, producing clusters of small, creamy-white flowers. These blossoms later turn into black, ornamental berries, adding an additional level of visual interest.


Types and Varieties

There are several varieties of Japanese Aralia, each with its unique features:

  1. Fatsia japonica ‘Variegata’: This variety is sought after for its variegated leaves that boast a mixture of green, cream, and sometimes yellow hues.
  2. Fatsia japonica ‘Spider’s Web’: As the name suggests, this variety’s leaves are speckled with a web-like pattern, giving it a distinctive appearance.
  3. Fatsia japonica ‘Murakumo Nishiki’: Known for its vibrant yellow-golden leaves, this variety adds a bright touch to any space.
  4. Fatsia japonica ‘Annelise’: This variety features leaves with creamy white patches, creating a striking contrast against the deep green.

Facts about the Plant

  1. Named for Its Leaves: The name ‘Fatsia’ is derived from the ancient Japanese words for eight (‘fat’) and leaf (‘sa’), referring to the plant’s eight-lobed leaves.
  2. Tolerates Low Light: Japanese Aralia can thrive in low light conditions, making it an excellent choice for rooms with few windows or for adding greenery to shaded areas in the garden.
  3. Attracts Pollinators: When grown outdoors, the blossoms of the Japanese Aralia attract various pollinators, contributing to the local ecosystem.
  4. Historical Use: In the past, the leaves of Japanese Aralia were used to make Japanese traditional paper, called ‘washi’.
  5. Not Pet-Friendly: Japanese Aralia is toxic if ingested by pets. Therefore, pet owners should consider placing the plant out of their pets’ reach.

Tips to Grow Japanese Aralia

Growing Japanese Aralia successfully involves understanding its natural habitat and mimicking those conditions. Here are some expert tips:

  1. Light Requirements: Though Japanese Aralia tolerates low light, it prefers bright, indirect light for optimal growth. A north or east-facing window is ideal.
  2. Watering: Water thoroughly and allow the top inch of soil to dry out between watering. Overwatering can lead to root rot, a common issue with this plant.
  3. Humidity: Japanese Aralia thrives in humid environments. Mist your plant regularly, use a pebble tray, or consider using a humidifier, especially during dry seasons.
  4. Soil: Use a well-draining, fertile soil mix. Adding some organic matter or compost to the soil will enhance its nutrient content.
  5. Feeding: Feed the plant with a balanced houseplant fertilizer every month during the growing season (spring and summer).
  6. Pruning: Prune the plant in late winter or early spring to maintain its shape and size. You can also remove any yellowed or diseased leaves to keep the plant healthy.

Major Problems

While Japanese Aralia is a relatively easy plant to care for, it is not without its issues.

  1. Overwatering: This is the most common problem, leading to root rot. Symptoms include yellowing leaves and a wilted appearance even with adequate water.
  2. Spider Mites and Aphids: These pests can infest the plant, especially in dry conditions. Check regularly under the leaves and treat with a suitable insecticide or soapy water if needed.
  3. Leaf Spot: This fungal disease is caused by excessive moisture on the leaves. Water your Aralia at the base to avoid this problem.
  4. Frost Damage: If grown outdoors, Japanese Aralia can suffer from frost damage. It is best to move the plant indoors or cover it during freezing temperatures.
  5. Leggy Growth: Inadequate light can cause your plant to become ‘leggy’, with long, thin stems and fewer leaves. Move the plant to a brighter location to correct this.

Care and Maintenance

Japanese Aralia is not a particularly demanding plant when it comes to care and maintenance. Here are some key considerations:

Japanese Aralia
  1. Light: Provide bright, indirect light. Too much direct sunlight can cause leaf burn, while too little can lead to leggy growth.
  2. Watering: Allow the top inch of the soil to dry out between waterings to avoid root rot. Water less in the winter months.
  3. Humidity: Maintain high humidity around the plant. This can be achieved by regular misting, using a pebble tray with water, or placing a humidifier in the room.
  4. Fertilization: Feed your Aralia with a balanced houseplant fertilizer every month during the growing season.
  5. Pruning: Prune in late winter or early spring to maintain a compact shape. Remove any yellow or diseased leaves to keep the plant healthy.
  6. Repotting: Repot every 2-3 years in the spring to refresh the soil and give the plant more space to grow.
