Grow Fatsia Japonica As a Houseplant
Grow Fatsia japonica ‘Spider’s Web’ for a gorgeous focal plant in your home.
Fatsia japonica, sometimes called Japanese aralia, is a shade-loving shrub that thrives in moist conditions. It’s usually grown for its outstanding foliage during the growing season. The huge leaves are deeply lobed and grow to nearly a foot wide. Fatsia grows up to 8 feet tall. The white flower clusters appear in fall, on mature plants, contributing to the beauty of a mature plant early in its lifecycle. Following them, in the winter, shiny, black fruit appear.
Fatsia likes slightly acid, nutrient-rich, moist soil. Also, it grows best in a shady location.
When stems that become spindly or leggy, simply cut them back. This encourages branching.
With proper conditions, Fatsia proves to be a low-maintenance plant. Also, pests seldom affect them.
Fatsia can be grown in beds or in containers both inside and out. It makes a bold addition to a courtyard or patio.
Fatsia japonica and Hedera helix (English Ivy) hybridize together to form Fatshedera lizei, also known as x Fatshedera lizei. The x denotes that the two parent plants represent different genus (Fatsia and Hedera). Thus the resulting plant, Fatshedera, remains sterile.

With broad, deeply lobed, dark green leaves held on stiff stems, Fatsia makes a bold landscape effect. It prefers a shady growing area. In fact, it might show the best at your home’s entry.
However, don’t rule out containers. Although Fatsia often grows large, it performs well in a large container.
Fatsia creates a dramatic effect with upright stems that bend and curve their way to about eight feet tall before their weight causes them to fall a bit horizontally.
In the fall, upright clusters of gorgeous creamy white flowers appear. These flowers attract bees and hummingbirds to their sweet nectar.
Then, toward winter, they produce shiny, black fruit. Though these fruit create an interesting contrast for several weeks, they prove inedible for people. However, birds find them quite attractive.
New sprouts appear toward the base of older stems. Keep them or remove to create new plants.
