Origin & Breeding History: 'Argyrayesi' originated from an open pollinated cross that took place in the summer of 2001, in Enkhuizen, The Netherlands. The female parent was a proprietary seedling selection and the male parent was an unidentified selection. The resultant seed was sown and the new variety was selected from the progeny in August 2002, based on the criteria for early flowering, flower colour, plant habit, branching and plant vigour. Asexual reproduction of the new variety by vegetative cuttings was first conducted in August 2002 in Enkhuizen, The Netherlands.
Tests & Trials: 'Argyrayesi' was tested during the spring of 2006 in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on March 30, 2006. Observations and measurements were taken from 10 plants of each variety on May 26, 2006. All colour measurements were made using the 2001 RHS colour chart.
