Alocasia longiloba ‘Purple’ – Care Guide

Light

Provide bright, indirect light for best growth. While this species appreciates plenty of light, direct sun can cause scorching, particularly on the delicate purple undersides of the leaves. Filtered light through a sheer curtain or an east-facing window is perfect.

Watering

Keep the soil evenly moist but not soggy. Water when the top 2–3 cm of soil feels dry to the touch, and ensure excess water drains away freely. Reduce watering during winter dormancy but do not allow the soil to dry out completely.

Temperature and Humidity

Temperature: Prefers warmth between 18–28 °C. Protect from drafts and avoid temperatures below 15 °C.
Humidity: High humidity (60–80%) is essential to prevent brown leaf edges. Mist regularly, use a humidifier, or group with other tropical plants to maintain consistent humidity.

Soil and Potting

Use a rich, well-draining aroid mix containing compost, perlite, orchid bark, and coco coir. This allows air to circulate around the roots while retaining enough moisture to mimic its rainforest habitat. Repot every 1–2 years in spring to refresh the growing medium.

Feeding

Feed every 4–6 weeks during spring and summer with a diluted, balanced fertiliser. Over-fertilising can cause leaf tip burn, so feed sparingly. Suspend feeding in autumn and winter.

Pruning and Maintenance

Remove any yellowing or damaged leaves near the base to maintain a tidy appearance. Wipe the leaves gently with a damp cloth to remove dust and reveal their sheen. Rotate occasionally to ensure even growth and prevent leaning toward the light.

Growth and Maturity

A moderate grower, Alocasia longiloba ‘Purple’ typically reaches 60–90 cm in height and 50–70 cm in spread indoors. Over time, it develops an upright, elegant habit with elongated, arrow-shaped leaves that arch gracefully from the base. During cooler months, it may enter dormancy — reduce watering and allow it to rest until new growth resumes.

Common Issues

• Yellowing leaves: Overwatering or poor drainage.

• Brown edges: Low humidity or inconsistent watering.

• Drooping leaves: Cold stress or lack of moisture.

• Pests: Occasionally affected by spider mites or thrips — treat with neem oil or insecticidal soap and maintain humidity.

Background and Benefits

Native to tropical Asia, Alocasia longiloba has been admired for centuries for its sculptural foliage and metallic tones. The ‘Purple’ form enhances these qualities with deeper, more dramatic colouration and a high-shine finish that makes it ideal for display in both contemporary and traditional interiors.

Like other Alocasias, it is well known for its air-purifying properties, helping to remove indoor pollutants and create a fresher living environment. Symbolically, it represents strength, vitality, and resilience — qualities embodied by its bold leaves and vigorous nature.
