Origin & Breeding History: 'Pouldom' originated from a cross between 'Korfalt' as the female parent and an unnamed seedling as the male parent. The cross was made in the summer of 1987 at Fredensborg, Denmark. Seeds from the cross were planted in December 1987 and germinated during the winter and early spring. 'Pouldom' was selected in the spring of 1988. Selection criteria included profusion of yellow flowers, almost continuous flowering, disease resistance and suitability to garden situations.

Tests & Trials: The test and trial for 'Pouldom' was conducted in the field during the summer of 2007 in St. Thomas, Ontario. The trial included 6 plants of each variety. Bare root plants were planted in 3 gallon containers and transplanted into the field in the fall of 2005. Plants were grown in rows with plants spaced 60 cm apart and rows spaced 90 cm apart. Observations and measurements were taken on July 26, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
