Alocasia longiloba ‘Silver’ is a stunning and elegant aroid prized for its elongated arrow-shaped leaves, cool-toned colouring, and beautifully contrasting silver veining. A member of the Araceae family and native to Southeast Asia, this cultivar showcases the classic longiloba silhouette but with a refined, shimmering twist.

The leaves are long, narrow, and deeply sagittate, with sharply defined lobes and a smooth, satin-like surface. Their colour ranges from deep blue-green to cool slate, overlaid with bold, metallic silver primary veins that highlight the angular, sculptural form of each leaf. The contrasting white to pale silver midrib creates a crisp, modern aesthetic, while the undersides often display soft purplish tones.

As the plant matures, it forms an upright rosette supported by mottled, slightly arching petioles that add further visual interest. Beautifully architectural and distinctly tropical, Alocasia longiloba ‘Silver’ is perfect for collectors who appreciate clean lines, refined foliage, and plants with a sophisticated presence.

Alocasia longiloba ‘Silver’ – Care Guide

Light

Thrives in bright, indirect light. The silver veining becomes more pronounced with good light levels. Medium light is tolerated but may result in greener, less dramatic leaves. Avoid harsh direct sun, which can scorch the foliage.

Watering

Keep the soil lightly and consistently moist. Allow the top 2–3 cm to dry between waterings, but avoid letting the plant fully dry out. Reduce watering slightly during winter when growth slows.

Temperature and Humidity

• Temperature: Prefers warm conditions of 18–26 °C. Avoid temperatures below 15 °C.

• Humidity: High humidity (60–80%) helps maintain crisp edges, richer colour, and larger leaves. A humidifier or grouped planting is beneficial.

Soil and Potting

Use a rich, airy aroid mix — a blend of houseplant compost, perlite, orchid bark, and coco coir. Excellent drainage prevents root rot. Repot every 1–2 years in spring, increasing the pot size only slightly.

Feeding

Feed every 2–3 weeks during the growing season with a balanced liquid fertiliser. Reduce feeding during winter.

Pruning and Maintenance

Remove older or yellowing leaves at the base to encourage fresh growth. Gently wipe the leaf surface to enhance the silver veining and gloss. Provide support if leaves become tall or arching.

Growth and Maturity

A moderate grower that typically reaches 40–70 cm in height. Mature plants develop more sharply defined leaves with stronger silver contrast and a fuller rosette. Growth slows in cooler conditions.

Common Issues

• Crispy edges: Low humidity or underwatering.

• Yellowing leaves: Overwatering or compacted soil.

• Soft stems/drooping: Cold temperatures or prolonged dryness.

• Pests: Watch for spider mites and thrips on the narrow leaves.
