The genus Heuchera includes at least 50 species of herbaceous perennial plants in the family Saxifragaceae, all native to North America. Common names include alumroot and coral bells. There is an extensive array of blossom sizes, shapes, and colors, foliage types, and geographic tolerances. New hybrid selections of Heuchera villosa have been bred specifically to tolerate the heat and humidity of the Southern US region.
Beginnings of Heucherella
A group of hybrids are formed by crossing Heuchera with Tiarella, this cross creates a group known as Heucherella. Heucheralla can have amazing foliage colors from the Heuchera parents and the dark leaf patterns and cut leaf shapes of the Tiarella parents. Most Heucherella form clumps or small mounds of evergreen foliage with upright flower stalks that can be anywhere from 8 to 24 inches long. They make their best foliage color displays in the cool seasons of spring or fall.
Growing Heuchera and Heucherella
Heuchera and heucherella have the same growing requirements. In warmer southern climates they are used as a shade loving perennial alongside hosta. Cooler climates can plant them in sun or shade. Soil sould be a well drained humus mixture with lots of organic matter.
