Origin & Breeding History: 'VDTG31' originated from an open pollinated cross between two unnamed parents, made in Lisse, The Netherlands in 2003. A single seedling was selected in the summer of 2004 in Lisse, based on criteria for single flower form, flower colour, compact plant habit and dark foliage colour. The variety was reproduced by cuttings in the Spring of 2005 in Lisse, The Netherlands.

Tests & Trials: The detailed description of 'VDTG31' is based on the UPOV report of Technical Examination, application number 2006/0570, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by The National Institute of Agricultural Botany (NIAB) in Cambridge, United Kingdom, in 2007. Colour determinations were made using the 1986 Royal Horticultural Society (RHS) Colour Chart.
