About

Colocasia esculenta 'Black Magic' is a stunning cultivar of the common Taro, widely grown for its dramatic and gothic foliage. The giant, heart-shaped (sagittate) leaves emerge dusty green but quickly mature to a deep matte charcoal-black or dark purple, with a velvety texture. Unlike Alocasias whose leaves point upwards, Colocasia leaves droop downwards, held on long, arching purple-black petioles that attach peltately near the leaf center. In optimal warm, wet conditions, it forms a large, majestic clump that feeds a substantial subterranean tuberous corm.

Before You Buy

Shared checklist for Colocasia esculenta and its cultivated forms

  • 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

Care Guide

Growing Conditions

General care shared across all forms of Colocasia esculenta — cultivated forms may need brighter light or higher humidity than the plain species; check this form's Quick Facts above.

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
