Heucherella or foamy bells is a hybrid derived from crossing U.S. native foamflower, (Tiarella spp.), with coral bell (Heuchera villosa), another U.S. native. Terra Nova Nurseries, a wholesale grower in Oregon, has introduced several of these hybrids. Heucherellas bring out the best traits of both parents. Their small creamy white, bell-shaped flowers open in late spring on sturdy stems which stand tall above the colorful foliage. Blooms attract numerous butterflies.

‘Sweet Tea’ foamy bells (Heucherella x ‘Sweet Tea’) is a true garden performer. Large 4-inch wide palmate leaves become an orange colored tapestry that changes from month to month. New spring leaves are bright orange. Some gardeners may opt to clip off flower stems to emphasize the rustic orange foliage colors. Leaves darken in the summer, and become a blend of orange and coppery shades in the autumn. Winter foliage is semi-evergreen in the Southern Appalachian region (USDA hardiness zones 6 and 7) and is fully evergreen further south.

Heucherella ask for very little maintenance. Sweet Tea grows 20 inches tall and 28 inches wide. It is best planted in organic rich, well-drained soil and in a partially shaded area. Irrigate a new planting over the first year and mulch around plants for additional moisture conservation. Sweet Tea tolerates summer’s heat and dry periods because of its H. villosa bloodline (USDA Zones 4–9).
