Origin & Breeding History: 'B10082' originated from the self-hybridization of an un-named proprietary variety designated 'B0901'. The hybridization was conducted in 2010 by Gert Kim Jensen in Marslev, Denmark. 'B10082' was selected in April 2011 for its attractive flowers and compact, upright growth habit.

Tests & Trials: The detailed description of 'B10082' is based on the UPOV Report of Technical Examination, application number 2012/0608, purchased from the Community Plant Variety Office in Anger, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2013. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
