Origin & Breeding History: The variety 'UF08174' originated from an open pollination conducted in Gainesville, Florida, USA in 2007. The female parent was the variety 'UF043633' and the male parent was unknown. The initial selection of 'UF08174' was made in May 2008, based on its consistent maroon coloured foliage accented with lime green coloured margins, mounded growth habit, overall vigour and late flowering. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: Trials for 'UF08174' were conducted in a polyhouse during the summer of 2012 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 14, 2012. Observations and measurements were taken from 10 plants of each variety on June 18, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
