Origin & Breeding History: The variety 'Yolake Placid' originated from a controlled pollination conducted in February 2003 in Salinas, California, USA. The female parent was a proprietary seedling designated YB-A3813 and the male parent was a proprietary seedling designated YB-A3951. The new variety was selected in November 2004 in Fort Myers, Florida. The selection criteria included flower colour and form, flowering response time, suitability for production, spreading growth habit, strong stems and excellent post production longevity. Asexual reproduction by vegetative tip cuttings was first conducted in Fort Myers, Florida, USA in February 2005.

Tests & Trials: Trials for 'Yolake Placid' 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 8, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
