The Olympia False Aralia is an elegant indoor plant, prized for its distinctive, finely divided foliage and graceful growth habit. Its unique aesthetic makes it a popular choice for enhancing interior spaces.
Understanding Olympia False Aralia
The Olympia False Aralia (Plerandra elegantissima), a member of the Araliaceae family, was previously known as Dizygotheca elegantissima and Schefflera elegantissima. This evergreen shrub is recognized for its delicate, deeply divided leaves, which emerge with coppery or burgundy hues before maturing into a vibrant dark green. Its narrow, oblong, irregularly serrated leaflets are arranged in a palmately compound fashion, giving the plant a feathery appearance.
Native to the wet tropical climates of New Caledonia, it thrives as an understory plant, preferring moderate light and high humidity indoors. While it can reach 6 to 25 feet outdoors, it typically grows to 5 to 6 feet indoors, making it a manageable size for most homes.
Caring for Olympia False Aralia
Light Needs
Olympia False Aralia flourishes in bright, indirect light. Place the plant near a south or west-facing window with sheer curtains to provide optimal lighting without harsh direct sun, which can scorch its delicate leaves. While it tolerates medium-light, growth may be slower and foliage less vibrant. Insufficient light can lead to dull green foliage or leggy growth.
Watering Practices
Maintain consistent soil moisture for Olympia False Aralia, but avoid soggy conditions, which lead to root rot. Water the plant when the top inch of soil feels dry. Use lukewarm, lime-free water and ensure the pot has adequate drainage holes to prevent waterlogging. Reduce watering frequency during winter when growth slows.
Soil Requirements
A well-draining, loamy soil mix that retains some moisture without becoming waterlogged is suitable. A blend of peat moss, perlite, and potting soil promotes proper drainage and aeration. Incorporating materials like perlite or vermiculite enhances airflow and prevents excessive moisture retention. The plant prefers slightly acidic to neutral soil conditions, with a pH of around 6.
Temperature and Humidity
Olympia False Aralia prefers warm, stable temperatures between 65°F to 85°F (18°C to 29°C). It is sensitive to cold; prolonged exposure below 60°F (15°C) can cause stress and leaf drop. High humidity levels (60-80%) are beneficial, reflecting its tropical origin. To increase humidity, use a pebble tray, group plants, or employ a room humidifier, as misting alone provides only temporary relief.
Fertilizing
Olympia False Aralia benefits from regular fertilization during its active growing season (spring and summer). Apply a balanced liquid fertilizer (10-10-10 or 3-1-2 ratio) monthly. Dilute the fertilizer to half strength to prevent over-fertilization, as these plants are sensitive. Reduce or cease feeding during fall and winter when growth slows.
Pruning
Pruning Olympia False Aralia helps maintain its shape, control size, and encourage bushier growth. The best time for pruning is during spring or early summer when the plant is actively growing. Remove any dead or damaged leaves and trim leggy stems to promote new shoots. For size control, pinch off the main stem’s tip to encourage lateral branching.
Repotting and Propagation
When and How to Repot
Repot Olympia False Aralia every two to three years, or when it shows signs of being root-bound (e.g., roots circling the pot or emerging from drainage holes). Spring is the best time, allowing the plant to recover and establish itself during its active growth phase. Choose a pot one size larger with good drainage. Gently remove the plant, loosen any compacted roots, and replant at the same depth with fresh, well-draining soil mix.
Propagation Methods
Olympia False Aralia propagates using stem cuttings. The best time to take cuttings is during spring or early summer. Select a healthy stem section with at least one node, and make a clean cut just below it. Remove any lower leaves that would be submerged. Place the cutting in a moist rooting medium (e.g., peat and perlite mix, or water), and maintain a warm, humid environment to encourage root development.
Common Problems and Solutions
Olympia False Aralia can show signs of distress, often related to improper environmental conditions. Leaf drop occurs due to sudden temperature changes, insufficient humidity, or overwatering. Yellow leaves indicate overwatering and potential root rot, requiring reduced watering frequency and proper drainage. Brown leaf tips or edges signal low humidity or inconsistent watering.
Pest infestations, such as spider mites, mealybugs, or scale, can affect False Aralia. Regularly inspect the foliage, especially the undersides of leaves, for early detection. If pests are identified, manage them by wiping leaves with a damp cloth or applying an insecticidal soap solution. Addressing environmental factors like humidity and consistent watering strengthens the plant’s natural defenses.
