Origin & Breeding History: 'VDTG26' was developed at the nursery of Fa. Gebr. Verwer, in Lisse, The Netherlands, and originated from the open pollinated cross between the female parent, a Dahlia plant identified as 'R', and pollen of an unidentified Dahlia plant. The cross took place in the summer of 2003. A single seedling was selected in the summer of 2004, based on criteria for flower form, colour, compact plant habit and dark foliage colour.
Tests & Trials: 'VDTG26' was tested in an outdoor trial during the spring of 2008 in St. Thomas, Ontario. The trial consisted of a total of 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 20 cm pots on May 15, 2008. Observations and measurements were taken from 10 plants of each variety on July 8, 2008. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
