Origin & Breeding History: The variety 'Red Yosonoma' originated from a naturally occurring whole plant mutation of the parent variety 'Yosonoma'. The variety was discovered and selected by the breeder in December 2005 in Fort Myers, Florida, USA. Selection was based on criteria for strong vigorous growth, foliage characteristics, flowering response time, flower form and colour, excellent flower production and suitability for production as a natural spray-type variety. Asexual reproduction by vegetative tip cuttings was first conducted in Fort Myers, Florida in March 2006.
Tests & Trials: Trials for 'Red Yosonoma' were conducted in a greenhouse trial during the Fall of 2011 in Niagara-on-the-Lake, Ontario. On August 8, 2011, fifty unrooted cuttings were directly stuck into 15 cm pots, with 5 cuttings per pot. The trial included a total of 10 pots of each variety spaced 30 cm apart. Plants were pinched once prior to short day treatment. Observations and measurements were taken from 10 plants of each variety on November 7, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
