Aralia elegantissima is grown for its attractive foliage. The long, narrow, dark green leaves with saw-tooth edges are coppery colored at first, but as they mature they turn dark green, appearing almost black on some plants. Bright light causes dark, blackish-green color on mature leaves. Aralia elegantissima is usually purchased as a tabletop plant, but with proper care, it can grow 5 to 6 feet tall over a period of several years.
Aralia elegantissima prefer to be located near a sunny window where they will receive bright to moderate light, but where the sun’s rays never fall directly on the plant. Direct sun can cause the leaf tips and edges to turn brown. You don’t have to adjust the thermostat when growing Aralia elegantissima indoors because the plant is comfortable at ordinary room temperatures of between 65 and 85 F. Be careful not to allow the plant to become chilled, however. The foliage suffers damage when temperatures fall below 60 F. Aralia elegantissima need regular watering and fertilizing. Give Aralia elegantissima water when the the soil is dry at a depth of 1 inch. Drench the pot with water and empty the saucer under the pot after the excess drains through. Fertilize every two weeks with liquid houseplant fertilizer in spring and summer and monthly in fall and winter. Repot Aralia elegantissima annually in spring using general purpose potting soil and a pot just big enough to accommodate the roots. Aralia elegantissima likes a tight pot. Since you will be growing a top-heavy plant in a relatively small container, choose a heavy pot or place a layer of gravel in the bottom to add weight and keep the plant from toppling.
