    How to Grow Heuchera: Complete UK Care Guide

    Heuchera is grown chiefly for its striking evergreen foliage, with leaf colour shifting depending on light levels, and works well in beds and pots alike.

    Heuchera, sometimes called coral bells, is grown primarily for its rounded, lobed evergreen foliage, available in shades from lime green and amber to deep purple and near-black, with tiny bell-shaped flowers held on wiry stems in early summer. Leaf colour intensity depends heavily on light levels, and plants are equally at home in borders or containers. The main pest to watch for is vine weevil, whose grubs can quietly destroy the root system over winter.

    Key takeaways

    • Heuchera is grown mainly for evergreen foliage in a wide range of colours.
    • Dark and purple varieties usually colour best in more sun; lime and gold prefer partial shade.
    • Vine weevil grubs are a serious threat, feeding on roots through autumn and winter.
    • Divide woody, congested clumps every three years in spring to keep plants vigorous.
    • Heuchera performs excellently in containers, giving year-round interest.

    Choosing varieties

    Heuchera cultivars vary enormously in leaf colour, so it helps to consider the light levels in your garden before choosing.

    Where and when to plant

    Plant heuchera in spring or autumn, choosing a spot to match the variety: darker, purple-leaved forms generally colour better with more sun, while lime and gold cultivars often prefer partial shade to avoid leaf scorch. It works well at the front of borders or as edging. Explore more planting combinations in our plants and seasonal guide sections.

    How to plant heuchera

    1. Choose a position with light levels suited to the variety's leaf colour.
    2. Improve soil with well-rotted organic matter if light or free-draining.
    3. Dig a hole a little larger than the root ball.
    4. Plant with the crown at or just above soil level, as heuchera dislikes deep planting.
    5. Backfill, firm gently and water in well.
    6. Space plants around 30cm apart to allow foliage to spread.

    Watering and feeding

    Water regularly while plants establish, then water during dry spells, as heuchera dislikes both drought and waterlogging. Apply a balanced liquid feed in spring and early summer to support strong foliage colour, feeding container-grown plants slightly more often through the growing season.

    Cutting back and deadheading

    Remove faded flower stems once they finish blooming to keep plants tidy. In spring, trim away any tatty or damaged leaves from winter weather, and lightly tidy the crown to encourage fresh new foliage to emerge.

    Dividing and propagation

    Heuchera crowns become woody and can lift out of the soil over a few years, reducing vigour. Divide congested clumps every three years or so in spring, discarding old woody centres and replanting healthy young sections slightly higher in refreshed soil, level with the crown.

    Growing in pots

    Heuchera is one of the best perennials for containers, giving colour and structure through every season. Use a peat-free, loam-based compost with added grit for drainage, and choose a pot at least 25cm in diameter. Position according to the variety's light needs and refresh the top layer of compost each spring.

    Heuchera FAQs

    Why has my heuchera lost its bright leaf colour?
    Heuchera foliage colour is strongly influenced by light. Purple and dark-leaved varieties often colour best in more sun, while lime and gold varieties can scorch in strong sun and colour better in partial shade.
    How do I know if vine weevil has attacked my heuchera?
    Adult vine weevils cause characteristic notches along leaf edges in summer, while their grubs feed on roots over winter, causing sudden wilting and collapse. Check the compost around the roots for creamy, C-shaped grubs.
    Can heuchera be grown in containers all year round?
    Yes, heuchera is an excellent evergreen container plant, providing colour through winter as well as summer, and pots make it easier to control soil quality and drainage.
    Is heuchera evergreen in the UK?
    Yes, most heuchera retain their foliage through a typical UK winter, though leaves may look tatty after hard frosts and can be tidied in spring.
    How often should heuchera be divided?
    Divide heuchera every three years or so in spring, as older plants can become woody at the base and benefit from being lifted, split and replanted more shallowly.
    Do heuchera need feeding?
    Heuchera are light feeders; a balanced liquid feed in spring and early summer is usually sufficient, with container-grown plants benefiting from slightly more regular feeding.
