Origin & Breeding History: 'Poulbambe' originated from a cross conducted in the summer of 1993 between the varieties 'Poultrav' and 'Poulurt'. The resulting seeds were planted in December of 1993 and germinated during the winter and early spring. The cross and selection took place in the greenhouses of Poulsen Roser A/S located in Fredensborg, Denmark. 'Poulbambe' was selected in the spring of 1994 based on the objective of this hybridization which was to create a new and distinct rose variety for use in the garden. Selection criteria included uniform and abundant amber yellow flowers, vigorous but compact growth when propagated both as a budded rose and on its own roots and disease resistance.

Tests & Trials: The test and trial for 'Poulbambe' was conducted during the summer of 2005 at BioFlora Inc. in St. Thomas, Ontario. There were 8 plants per variety. The roses were field planted in July of 2004 with the exception of 'Poulgode' which was field planted in the early spring of 2005. The rose plants were spaced 60 cm apart with a 90 cm row spacing. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten measurements.
