This plant does best in cool part day sun or shade with moderate to only occasional summer water once established and is cold hardy to about 10 degrees F. Although not extremely long lived, this is a wonderful plant that is worthy of replanting every 3-5 years for its lush foliage and colorful display of flowers. With its one drought tolerant parentage this cultivar is one of the Coral Bell cultivars most suitable for planting in dry shade and the flowers are very attractive to hummingbirds.

Heuchera 'Susanna' is a sister hybrid seeding of Heuchera 'Santa Ana Cardinal'. They are both hybrids that resulted from a cross between the Alum Root, Heuchera maxima and Coral Bells, Heuchera sanguinea and from these parents it inherited the larger stature, taller inflorescences and better drought tolerance of Heuchera maxima and the larger flower size of Heuchera sanguinea. It is one of a series that also includes 'Wendy', 'Genevieve', 'Opal' and 'Santa Ana Cardinal'. These were all bred by Dr. Lee Lenz in 1953 at Rancho Santa Ana Botanic Garden (now California Botanic Garden). This plant was introduced by John Dourly at the garden in 1974 and named for Susanna Bixby Bryant, the founder of the Rancho Santa Ana Botanic Garden.

In their book "Heuchera and Heucherellas: Coral Bells and Foamy Bells" Timber Press 2005 authors Dan Heims and Grahame Ware note that Linnaeus named Heuchera for Johann Heinrich von Heucher, professor of medicine and Botany at Wittenberg University and that the name Heuchera should be pronounced following this person's name that it commemorates, meaning it so be pronounced HOY-ker-uh, but like most people, we continue to pronounce it HUE-ker-ah. We grew this nice cultivar from 1994 until 1996 and only discontinued it after deciding this cultivar was very similar to Heuchera 'Santa Ana Cardinal' and that we were confusing customers (and ourselves) people by offering too many similar Heuchera cultivars. 

This information about Heuchera 'Susanna' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
