Alocasia clypeolata 'Green Shield' is a captivating Alocasia cultivar, valued for its uniquely textured, shield-shaped leaves and deep green coloration. This plant features thick, broad foliage with prominent, dark green veins that create a distinctive, raised, and puckered surface, resembling a reptile's skin or a carved shield. Its striking appearance makes it a popular choice for adding an exotic touch to indoor plant collections 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. Clypeolata means "small shield," referring to the leaf shape. 'Green Shield' is a cultivar name, aptly describing the plant's shield-like leaves and green colour.
Light: Alocasia clypeolata 'Green Shield' thrives in bright light that is not direct. Strong, direct sunlight can harm its leaves, potentially causing burning. Insufficient light may result in slower growth and less vibrant coloration. A position near a window with filtered light in a typical UK home is ideal.
Water: The potting mix should be kept consistently damp but not saturated. Allow the upper inch or two of the soil to dry between waterings. Ensure the pot drains exceptionally well to prevent root problems, which can be an issue, especially in the UK's climate. Reduce watering in autumn and winter when the plant's growth naturally slows or it enters dormancy.
Soil: An airy potting mix that drains well is essential. A mix specifically created for aroids, incorporating materials such as coco coir, perlite, and orchid bark, is often recommended to provide the necessary air circulation and drainage.
Fertilising: Use a diluted liquid fertiliser every two to four weeks during the active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 27°C (65°F and 80°F). It should be shielded from cold draughts and sudden temperature changes, which can occur indoors, particularly during colder UK months. Temperatures below 15°C (59°F) may trigger dormancy.
Humidity: Higher humidity levels are highly beneficial for Alocasia clypeolata 'Green Shield', ideally above 60%. Consider using a humidifier or placing the plant on a pebble tray with water to maintain optimal conditions, particularly during drier indoor periods in the UK.
Growth Habit: This Alocasia has an upright, clumping growth habit, with new leaves emerging from a central rhizome. It typically remains a manageable size, suitable for display on shelves or tabletops.
Toxicity: Like all Alocasias, this plant is toxic if consumed by humans or pets.
