Alocasia 'Tigrina', sometimes referred to as the Tiger Alocasia, is a distinctive and appealing aroid, valued for its uniquely patterned stems and striking foliage. This Alocasia cultivar features arrow-shaped or shield-shaped leaves of deep green, often with prominent, light green or silvery veins. Its most notable characteristic is its striped petioles (leaf stems), which display dark bands resembling tiger stripes. This combination creates an exotic and dramatic appearance, making it a popular choice for 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. 'Tigrina' is a cultivar name referring to the tiger-stripe-like pattern on its stems.
Light: Alocasia 'Tigrina' thrives in bright, indirect light. Strong, direct sunlight can scorch its leaves, while insufficient light may result in slower growth and less vibrant coloration, diminishing its characteristic patterns. A position near a window with filtered light in a typical UK home is ideal.
Water: The potting mix should be kept consistently moist but not saturated. Allow the upper inch or two 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 four 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 'Tigrina'. 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 or corm. It can attain a moderate size indoors, making it a prominent feature.
Toxicity: Like all Alocasias, this plant is toxic if ingested by humans or pets.
