Heucherella plants are a fairly new genus of evergreen perennial made by crossing Heuchera (Coral Bells) and the closely related Tiarella (Foamflower). They offer many of the benefits of both of their parents - they have the same beautiful, heart-shaped foliage as Heuchera albeit the leaves tend to be a little smaller, as well as delicate, light foamy flowers reminiscent of the foamflower in shades of pink, cream and white. Like Heuchera, they are grown for their interesting, vibrant foliage. There are a wide range of varieties available, some with a single foliage colour, others two-toned with beautiful, prominent variegation. Lighter coloured heucherella generally prefer partial or dappled shade to provide some protection from the sun, especially in warmer southern parts of the UK, whilst the foliage of darker-coloured varieties is most vivid with more direct sunlight. Low growing to around 30-50cm tall, Heucherella are popular plants for adding tone and texture to borders, rockeries or patio containers. Best grown in groups of the same variety to create stunning 'waves' of colour. They're easy to grow - just give the foliage some light maintenance in the spring to keep it looking tidy.
