Description

Heuchera ‘Melting Fire’ is one of the darkest, most dramatic heucheras available — deeply ruffled leaves in a rich burgundy-red that deepens almost to black in cooler months, with a subtle metallic sheen that catches the light beautifully. It’s evergreen, so that intensity of colour is present all year round, not just through summer. Slender wiry stems carry small creamy-white flowers above the foliage in late spring, adding a delicate contrast to the bold leaves beneath. Compact, versatile, and genuinely striking — equally at home in a shaded border, a container, or woven through a mixed planting where its deep colouring creates contrast against greens and silvers.

Caragh Garden Notebook

Planting:
Plant in spring or autumn into moist, well-drained soil enriched with organic matter. Heucheras prefer a position with some shade, particularly protection from harsh afternoon sun which can scorch the foliage. Space plants 40–50cm apart and plant at the same depth as they were in the pot — planting too deep can cause the crown to rot.

Watering:
Water regularly through the first season and during dry spells. ‘Melting Fire’ performs best with consistent moisture — the foliage colour is richest and most vibrant when plants are not stressed by drought. In containers, check moisture levels regularly through summer.

Feeding:
A light mulch of compost in spring is sufficient in the ground. In containers, apply a balanced slow-release feed in spring to support healthy foliage through the season. Avoid high-nitrogen feeds which encourage soft, leggy growth.

Seasonal Care & Tidy-Up:
Heucheras are largely self-maintaining. In early spring, tidy away any tired or winter-damaged outer leaves and lift the crown gently if it has pushed itself out of the soil — a natural tendency over time. Firm back in and top-dress with fresh compost.

Division (to keep plants vigorous):
Divide every 3–4 years in spring to keep plants compact and vigorous. Heucheras can become woody and congested over time — division refreshes them and gives you new plants to spread through the border or containers.

Pests & Problems:
Generally trouble-free. Vine weevil can be a problem, particularly in containers — the grubs feed on roots through winter and can cause sudden collapse of the plant. Use vine weevil biological control or nematodes in late summer as a preventative measure. Ensure good drainage to avoid crown rot, especially through winter.

Design Notes:
The deep burgundy-black foliage of ‘Melting Fire’ creates stunning contrast against silver, lime-green, and cream — try it alongside Carex ‘Ice Dance’, Alchemilla mollis, or Athyrium ‘Silver Falls’ for a sophisticated shade planting with real year-round impact. Also works beautifully at the front of a sunny or part-shaded border where the dark leaves add depth and anchor lighter, airier plants around it. Excellent in containers either as a standalone specimen or combined with trailing plants and contrasting foliage. The colour intensifies in autumn and winter, making it one of the most valuable plants in the garden when everything else is dying back.
