Colocasia ‘Black Coral’ – A Delight for Any English Garden

Colocasia ‘Black Coral’: Bold Foliage for a Stunning English Garden

Colocasia ‘Black Coral’ is a dramatic foliage plant that transforms borders, pondsides, and tropical‑themed gardens. With its near‑black, heart‑shaped leaves and impressive height, it delivers instant impact while remaining surprisingly easy to grow in UK conditions.

Key Features

Striking Foliage

Large, paddle‑shaped leaves in deep blue‑green to jet‑black shades bring rich, architectural structure to any planting scheme.

Impressive Height

Growing between 3–5 feet tall, it stands proudly as a focal point or dramatic backdrop in borders.

Occasional Flowers

Though mainly grown for its foliage, it sometimes produces exotic spathes, adding subtle charm to the plant’s tropical character.

Care Tips

Light

Prefers partial shade to full sun. In very bright spots, intense midday sun can scorch the leaves, so dappled shade is ideal.

Soil

Thrives in rich, moisture‑retentive, well‑draining soil. Adding compost or organic matter improves performance and leaf size.

Watering

Colocasia loves consistently moist conditions — never allow the soil to completely dry out. Perfect for damp borders or near water features.

Garden Uses

Borders & Beds

Use as a statement plant to add height, texture, and contrast, especially alongside lighter green or variegated plants.

Water Features

Ideal for planting near ponds, bog gardens, or streams, where the roots can enjoy consistent moisture.

Tropical Themes

Pairs beautifully with bananas, cannas, hostas, ferns, and bold summer perennials to create a lush, exotic feel.

FAQs

Is Colocasia ‘Black Coral’ hardy in the UK?

It’s frost‑tender. In colder regions, lift the tubers before winter or overwinter the plant in a greenhouse. In mild coastal areas, a very thick mulch may protect it.

Can I grow it in a pot?

Yes — choose a large container, use rich compost, and keep it well‑watered. Container plants may need even more frequent watering.

Why are the leaves turning yellow?

Common causes include under‑watering, cold drafts, or nutrient deficiency. Ensure warmth, consistent moisture, and occasional feeding.

Does it need feeding?

A high‑nitrogen liquid feed every 2–3 weeks in summer encourages big, glossy leaves.

How much sun does it need?

Partial shade is ideal. Too much direct midday sun may scorch the foliage, but morning or late‑day sun helps maintain rich colour.
