Origin & Breeding History: 'Datretten' originated from a cross made in 2003 at Odense, Denmark. The female parent was a proprietary selection designated 01.149L and the male parent was the variety 'Daseks'. The breeder selected the new variety from the progeny of this cross on the basis of compact form and free flowering habit.

Tests & Trials: The detailed description of 'Datretten' is based on the UPOV report of Technical Examination, application number 2006/0527, 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.
