Origin & Breeding History: 'Poulyc001' originated from a cross conducted in the spring of 1991 between an unnamed seedling and variety 'Bonica 82'. The resulting seeds were planted in December of 1991 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. 'Poulyc001' was selected in the spring of 1992 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 flowers appearing on the plant evenly from the lower to upper branches, vigorous but compact and low growth when propagated both as a budded rose and on its own roots, disease resistance and climbing plant growth habit.

Tests & Trials: The test and trial for 'Poulyc001' was conducted during the summer of 2005 at BioFlora Inc. in St. Thomas, Ontario. There were 8 plants per variety. The candidate variety was field planted in July of 2004 and the reference variety was field planted in the May of 2003. 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.
