Origin & Breeding History: 'VDTG61' originated from an open pollinated cross between the female parent, a Dahlia plant identified as 'R', and an unidentified male parent. The cross took place in the summer of 2003 in Lisse, The Netherlands. A single seedling was selected in the summer of 2004 based on criteria for flower form, flower colour, compact plant habit and dark foliage colour. Asexual propagation by cuttings was first conducted in Lisse, The Netherlands, in the spring of 2005.

Tests & Trials: Trials for 'VDTG61' were conducted in a polyhouse during the spring/summer of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 15, 2008. Observations and measurements were taken from 10 plants of each variety on July 8, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
