Heucheras, Heucherellas and Tiarellas Heucheras and Tiarellas 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 popular for floral art. While not slug resistant, in our experience they are rarely damaged. Heuchera Peach Flambé Heucheras are invaluable evergreen 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 15-60 cm, while the stems of flowers reach 15-90 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. To maintain good plants we advise customers to lift Heucheras and replant them 8-10 cm deeper, burying the woody stems that tend to grow out of the crown. The plants can also be divided at this stage. Some people prefer to cut off flower spikes as they appear to maintain a better-shaped plant. Heuchera Peachy Keen Tiarellas prefer full or partial shade, and will tolerate dry soil, and they are a good choice for ground-cover. Their palmate leaves are green, often patterned with dark markings, and pretty star-shaped flowers are produced from spring onwards. Dead heading by pulling off flower spikes at their base prolongs flowering. 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. Heucherella Stoplight New for this season are outstanding Heucheras direct from Terra Nova Nurseries in Oregon, U.S.A. We have been assessing them over the past months ready for your garden in 2005. In our opinion the stars are Heuchera "Peachy Keen" with wildly splashed leaves of pink, red and orange shades, and Heuchera "Peach Flambé" with bright peachy-orange leaves. Heucherella "Stoplight" is an improved version of "Sunspot" with a stronger red centre and a brighter leaf. Add these to last year’s stars, Heucheras "Marmalade" and "Lime Ricky", and we are delighted to present to you a selection of Heucheras, Heucherellas and Tiarellas that is second to none.
