In the garden

_ Heucherella alba sits in the genus Heucherella within the saxifrage family (Saxifragaceae) and is grown as a perennial foliage and flowering plant. Its form and cultural requirements make it particularly appropriate where shade and consistent moisture limit the choice of understorey perennials. The plant is classed H5 for UK hardiness, meaning it is hardy in most garden situations. Place _ Heucherella alba in partial shade or full shade where it will not dry out. It prefers well-drained, humus-rich soil that retains moisture; aim for a neutral to slightly acidic pH. Although the soil should be freely draining, regular moisture through the growing season helps foliage remain healthy and prevents stress in drier spells. In colder months the H5 rating indicates the plant will tolerate typical UK winters without special winter protection. Use this Heucherella at the front of a border, as a low ground cover beneath larger shrubs, or in a dedicated shade garden where other sun-loving perennials struggle. Maintain a layer of organic mulch to conserve soil moisture and replenish humus over time. Flowering takes place from May to July, providing late spring to early-summer interest above the leaves.
