About Colocasia esculenta 'Black Coral'
Black Coral is similar in size and glossy leaf form to Diamond Head, but pushes the colour even further into an even darker, blacker leaf with a subtle bluish glossy sheen along the venation. It's a patented, long-stalked selection with heart-shaped jet-black leaves that reads as one of the most intensely dark Colocasia cultivars in cultivation.

Before you buy
- 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
Colocasia esculenta 'Black Coral' care
- 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.
- Feeding
- 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
Yellowing lower leaves
Cause: Natural leaf turnover as the plant grows
Fix: Remove spent leaves; only investigate if multiple leaves yellow at once
Spider mites
Cause: Dry indoor air
Fix: Increase humidity and treat with insecticidal soap
