Origin & Breeding History: 'Poultc012' originated from the controlled crossing in 1996 of the female parent, 'Pouldiram' with an unnamed male parent in Fredensborg, Denmark. One seedling resulting from this cross was selected in the spring of 1997 based on uniform and vigorous growth when propagated on own root, flower colour, attractive foliage, suitability for container culture and resistance to diseases.

Tests & Trials: Field trials were conducted during the summer of 2008 in St. Thomas, Ontario. There were 8 plants of each variety planted in May 2007 in rows with plants spaced 2 feet apart and rows spaced 3 feet apart. All colour measurements were made using the Royal Horticultural Society Colour Chart 2001.
