Origin & Breeding History: The variety 'Syngold Emporia' originated from a controlled pollination conducted in February 2002 in Salinas, California, USA. The female parent was designated YB-F0125, a proprietary seedling with grainy orange flower colour and the male parent was designated YB-6604, a proprietary seedling with yellow flower colour. The resultant seed was sown in Alva, Florida, USA and the new variety was selected as a single plant from the progeny in February 2006 in Alva, Florida. The selection criteria included flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'Syngold Emporia' 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.
