'Poulcs010' was selected in the spring of 1993. Selection criteria included uniform and abundant orange red flowers, vigorous but compact growth habit, disease resistance and attractive dark coloured foliage.

Tests & Trials: The test and trial for 'Poulcs010' 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 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.
