Origin & Breeding History: 'TNHEU043' was developed by the breeder, an employee of Terra Nova Nurseries, Inc., in Canby, Oregon. The new variety originated from a controlled cross that took place in May 2001, between the Heuchera variety 'Amber Waves' as the female parent and the Heuchera variety 'Huntsman' as the male parent. The new variety was selected from the progeny of this cross in May 2003, based on leaf colour, winter leaf colour, flower colour and plant habit.
Tests & Trials: The tests and trials for 'TNHEU043' were conducted in a polyhouse during the summer of 2006 in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 10, 2006. Observations and measurements were taken from 10 plants of each variety on July 14, 2006. All colour measurements were made using the RHS Colour Chart 2001.
