Origin & Breeding History: 'Poulcas024' originated from the controlled crossing in 1995 of an unnamed female parent with the male parent, 'Poulcs007' in Fredensborg, Denmark. One seedling resulting from this cross was selected in the spring of 1996 based on compact uniform growth when propagated on own root, flower colour, flower longevity, 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.
