Origin & Breeding History: 'Poulcy015' originated from a controlled cross conducted during the summer of 1998 at the breeding facilities of Poulsen Roser A/S in Fredensborg, Denmark, as part of a breeding program to hybridize rose varieties for commercial glasshouse and nursery culture. The cross involved two unnamed seedlings. The resultant seeds were planted in December 1998 and germinated during the winter and early spring. In the spring of 2000, one seedling was selected for its compact and vigorous growth when propagated on its own root, profusion of red flowers, suitability to open air nursery container culture, resistance to typical rose diseases, and as a climbing type rose with reduced apical dominance.

Tests & Trials: The comparative trial for 'Poulcy015' was conducted in a polyhouse during the spring of 2014 at BioFlora Inc. in St. Thomas, Ontario. The trial consisted of a total of 8 plants of the candidate variety and 6 plants of the reference variety. All plants were grown from bare-rooted plants and transplanted into 13 litre containers on April 4, 2014. Unless otherwise indicated, observations and measurements were taken from 8 plants or 10 parts of plants of the candidate variety on June 17, 2014, and 6 plants or 10 parts of plants of the reference variety on June 20, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
