Origin & Breeding History: 'Granyel' was bred and developed through inbred breeding of the Gaillardia aristata variety 'Burgundy'. The breeder conducted 3 cycles of half-sib selections of the variety 'Burgundy' during the period from August 1999 through to July 2001, in Enkhuizen, The Netherlands. The seeds from the selection were sown in January 2002 and a single seedling was selected in July 2002. The selection criteria included compact plant habit, good branching characteristics and early flowering. Asexual reproduction by cuttings was first conducted in August 2002 in Enkhuizen, The Netherlands.

Tests & Trials: Trials for 'Granyel' were conducted during the summer of 2008 in a polyhouse at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants each of the candidate and reference varieties. The plants were grown from rooted cuttings which were transplanted into 1 gallon pots on April 17, 2008. Observations and measurements were taken from 10 plants on June 26, 2008. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
