Heucheras and Heucherellas Heucheras originated as woodland plants in North America, and are well-suited to British gardens, with their attractive leaves providing an ideal foil for other herbaceous plants. The leaves with varied colours and patterns are increasingly used in floral art. While not slug-proof, in our experience they are rarely damaged, and customers tell us that they are seldom targeted by rabbits. Heucheras are invaluable ever-green foliage plants for the garden, where they can be used in the herbaceous border, in containers, or even in hanging baskets. Depending on the cultivar, the size of the mound of foliage varies from 15 cm to 60 cm, while the stems of flowers reach 15cm to 90 cm tall. Heucheras require a moist but well-drained soil in sun or partial shade. Purple foliage cultivars with marbled or marked leaves keep their contrast best in full sun. Cultivars with yellow foliage require part or full shade as the leaves are prone to scorching. To maintain well-shaped plants we advise customers to lift Heucheras and re-plant them 8cm to 10cm deeper, burying the woody stems that tend to grow out of the crown. The plants can also be divided at this stage. Heucherellas are produced by crossing Heucheras and Tiarellas, and generally have Tiarella-type flowers with Heuchera foliage. They have the same cultural requirements as Heucheras.
