Heuchera - Heucherella
Heuchera or Coral bells are easy to grow and blend easily with most other perennials in the landscape. Because of their low, mounding habit, they are often used as edging along paths or in containers. Try cutting a few of the tall flower scapes for fresh bouquets. The heuchera we grow will tolerate the heat of the South and many will take partial sun. Their lush foliage remains evergreen or semi-evergreen throughout the winter where we have had temperatures into the teens for several day.
Heucherella or foamy bells it is the result of a cross between two distinct genera, Heuchera and Tiarella, and shows similarities to both parents. This type of intergeneric hybrid is quite rare, and is indicated by a multiplication symbol before the name. The name Heucherella is an example of a portmanteau word, a combination of the two parents' names.
Heucherellas form clumps or small mounds of evergreen foliage with upright flower stalks 8–24 in long. Most heucherella prefer partial shade, though the newer strains are more sun tolerant. They prefer well-drained organic soils and regular watering. They send up new growth every year in spring. Our heucherella tolerate some sun and tolerate heat better than other varieties.
