Alocasia macrorrhiza 'Aurea Variegated' is a stunning and sought-after cultivar, prized for its large, glossy leaves adorned with striking yellow or creamy variegation. This Alocasia features broad, heart-shaped or shield-shaped foliage with irregular patterns of bright yellow blending with shades of green, creating a vibrant and eye-catching display. Its impressive size and distinctive coloration make it a dramatic centrepiece for any indoor plant collection in the UK. It is a member of the Araceae family.
The genus name Alocasia comes from Greek words, indicating a distinction from the taro plant. Macrorrhiza translates to "large root," referring to the plant's substantial underground rhizomes. 'Aurea Variegated' describes the gold or yellow variegated patterns on its leaves.
Light: Alocasia macrorrhiza 'Aurea Variegated' thrives in very bright, indirect light. Strong, direct sunlight can scorch its leaves and diminish the variegation, while insufficient light may result in slower growth and faded patterns. A position near a window with filtered light is ideal for UK homes.
Water: The potting mix should be kept consistently moist but not saturated. Allow the upper half of the soil to dry between waterings. Ensure the pot has excellent drainage to prevent root issues, which can be a common problem, especially in the UK's climate.
Soil: An airy and well-draining potting mix is essential. A mix specifically formulated for aroids, incorporating materials such as coco coir, perlite, and orchid bark, is often recommended to provide the necessary aeration and drainage.
Fertilising: Use a diluted liquid fertiliser every two to three weeks during the active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months when the plant's growth naturally slows or it enters dormancy.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 27°C (65°F and 80°F). It should be shielded from cold drafts and sudden temperature changes, which can occur indoors, particularly during colder UK months.
Humidity: Higher humidity levels are highly beneficial for Alocasia macrorrhiza 'Aurea Variegated'. Consider using a humidifier or placing the plant on a pebble tray with water to maintain optimal conditions, especially during drier indoor periods in the UK.
Growth Habit: This Alocasia has an upright, herbaceous growth habit, often developing a thick, self-supporting trunk over time. It can grow to a considerable size indoors, making it a prominent feature.
Toxicity: Like all Alocasias, this plant is toxic if ingested by humans or pets, as it contains calcium oxalate crystals. Keep it out of reach of children and animals.
