Heuchera 'Kassandra' is a hybrid that was the result of crossing the Heuchera villosa hybrid 'Caramel' PP 16,560 with Heuchera 'Mocha' in a controlled breeding program at Pepinieres Delabroye, the nursery of Thierry and Sandrine Delabroye in Hantay, France. It was selected for its compact mounding habit, foliage color and good tolerance to heat, humidity, and exposure to sunlight. This plant received its US Plant Patent on November 9, 2010. 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 2011 to 2016. 

This information about Heuchera 'Kassandra' PP21,466 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.
