Origin & Breeding History: 'Argypri' originated from an open pollination that took place in August 2002 in Enkhuizen, The Netherlands, between the female parent identified as E0135-1 and pollen from an unidentified Argyranthemum frutescens. The variety was bred and developed by the breeder Anna M.W.P. Houbraken, while employed at Syngenta Seeds B.V., Enkhuizen, The Netherlands. The new variety was selected as a single seedling in August 2003 based on plant growth habit and flower colour. Asexual reproduction of 'Argypri' was first conducted by cuttings in August 2003 in Enkhuizen, The Netherlands.
Tests & Trials: Trials for 'Argypri' were conducted in a polyhouse during the spring of 2008 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 11 cm pots on March 19, 2008. Observations and measurements were taken from 10 plants of each variety on May 23, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
