Origin & Breeding History: 'Yopatagonia' is the product of a planned breeding program conducted by Yoder Brothers Inc. 'Yopatagonia' originated from a cross pollination in February 1999 in Salinas, California, USA, of the proprietary seedling selections coded YB-4065 as the female parent and YB-6489 as the male parent. It was discovered and selected in November 1999 as a single flowering plant within the progeny of the stated cross. Selection criteria included growth habit, inflorescence form, floret colours, response time and postproduction longevity.

Tests & Trials: The detailed description of 'Yopatagonia' is based on the UPOV report of Technical Examination, CPVO reference number 2004/0566, grant number 16215. The trials were conducted by NIAB, in Cambridge, UK in 2004. Colour determinations were made using the 1986 Royal Horticultural Society (RHS) Colour Chart.
