Origin & Breeding History: 'Deppe' originated from an open pollination made in the summer of 2002 in Grand Haven, Michigan, USA. The female parent was the variety 'Gemo' and the male parent was unknown. The new variety was selected from the progeny in the summer of 2004, based on criteria for compact growth habit, good flower production and foliage colour. Asexual reproduction by softwood cuttings was first conducted in 2004 in Grand Haven, Michigan, USA.
Tests & Trials: Trials for 'Deppe' were conducted in a polyhouse during the spring/summer of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and 10 plants of the reference variety. All plants were grown from 2 1/4 inch rooted liners transplanted into 2 gallon containers on June 3, 2007, and repotted into 3 gallon containers on June 2, 2008. Measured characteristics were based on measurements taken from 10 plants or parts of plants on July 25, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
