About

Colocasia esculenta, Taro, is one of the oldest cultivated plants in the world, grown for its starchy corm as a staple food crop across the tropics for thousands of years. As an ornamental it is prized for its immense, heart-shaped, softly matte leaves on tall upright petioles, forming a dramatic architectural clump in the garden or as a large houseplant. The plain species is solid green; named colour selections bred from it — most famously the near-black 'Black Magic' — have made Colocasia a popular subject for dramatic foliage colour breeding, distinct from the closely related but visually different Alocasia genus.

Before You Buy

Species-specific things to check when evaluating a listing

  • The plain species is inexpensive and widely available as corms or potted plants each spring
  • For 'Black Magic' or other named colour selections, confirm the leaf colour in photos matches the named form
  • Check corms are firm, not soft or mouldy, if buying bare-root
  • All parts contain calcium oxalate crystals and are toxic if ingested raw — keep away from pets and children

True From Cuttings
Yes

Cultivar character is preserved through vegetative cuttings

Produces offset cormlets readily, which separate easily from the parent corm. One of the easiest aroids to divide.

Care Guide

Growing Conditions

Substrate

Rich, moisture-retentive mix: 50% potting compost, 30% loam, 20% perlite. Tolerates boggy conditions better than most aroids.

Watering

Keep consistently moist — this species tolerates and often prefers wetter soil than typical houseplants, even standing water at the base outdoors.

Humidity

50-70%, tolerates average household humidity well outdoors or in bright rooms.

Fertilising

Balanced liquid fertiliser at full strength every 2-3 weeks during the growing season — a hungry, fast-growing plant.

Repotting

Annually while actively growing, given its rapid growth and corm expansion.

Common Problems

Problem

Yellowing lower leaves

Cause

Natural leaf turnover as the plant grows

Fix

Remove spent leaves; only investigate if multiple leaves yellow at once

Problem

Spider mites

Cause

Dry indoor air

Fix

Increase humidity and treat with insecticidal soap
