Heucherella

Heucherella, commonly called foamy bells, is a garden hybrid of Heuchera and Tiarella grown for lobed, often patterned leaves and airy sprays of small flowers. Cultivars vary widely in size, foliage color, sun tolerance, and seasonal persistence, so choose a named selection when a specific mature size or color is important. The [RHS](https://www.rhs.org.uk/plants/163137/%C3%97-heucherella-kimono/details) describes the hybrid group, and [Garden Design](https://www.gardendesign.com/perennials/heucherella.html) summarizes its landscape uses. ## Garden placement Most forms make clumps or low mounds for shaded borders, woodland gardens, rock gardens, containers, or groundcover beneath shrubs. Foliage ranges among lime, gold, bronze, red, and silver tones; slender stems carry small white, pink, or cream flowers, usually from late spring into early summer. Mature size differs by cultivar, with compact forms and wider spreading selections both available. Many grow best in partial or dappled shade and humus-rich soil that drains well while staying lightly moist. Avoid burying the crown or leaving the roots in soggy ground. [Greenhouse Grower](https://www.greenhousegrower.com/crops/how-to-grow-heucherella/) notes that size and sun tolerance differ considerably between cultivars. ## Maintenance Water regularly while plants establish and during summer dry spells, but keep drainage open. Trim winter-damaged leaves in early spring and remove spent flower stems after bloom. Divide mature clumps every three to four years in spring or fall to refresh growth; in cold regions, a light mulch after the ground freezes can reduce frost heaving. These care practices are summarized in the [Heucherella growing guide](https://www.gardendesign.com/perennials/heucherella.html).
