Origin & Breeding History: The variety 'Yopueblo' originated from a controlled pollination conducted in January 2004 in Salinas, California, USA. The female parent was a proprietary seedling designated YB-A4929 and the male parent was a proprietary seedling designated YB-A3803. The new variety was selected in Fort Myers, Florida, USA in March 2005. The selection criteria included growth habit, strong stems, flowering response time, flower form and colour and excellent post production longevity. Asexual reproduction by vegetative tip cuttings was first conducted in Fort Myers, Florida in June 2005.

Tests & Trials: Trials for 'Yopueblo' were conducted in a greenhouse trial during the Fall of 2011 in Niagara-on-the-Lake, Ontario. On August 16, 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.
