Origin & Breeding History: 'DG09-4' originated from a cross conducted by the breeder Charles Valin, an employee of Thompson and Morgan Ltd. (A Division of Branded Garden Products Ltd.), as part of a controlled breeding program in Ipswich, United Kingdom during the summer of 2008. The cross involved the unpatented lines, 'DG05006' as the female parent, and 'DG05043' as the male parent. From the resulting progeny, 'DG09-4' was selected by the breeder for its continuous flowering, sterile flowers, dark pink with apricot tinged flower colour and deeply serrated leaves.

Tests & Trials: The comparative trial for 'DG09-4' was conducted in a polyhouse during the summer of 2015 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings transplanted into 4.4 liter containers on April 21, 2015. The observations and measurements were taken from 10 plants, or parts of plants, of 'DG09-4' on July 28, 2015 and of 'Waldigone' on July 2, 2015. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
