Origin & Breeding History: 'G13518' was bred and developed by the breeder, Michael S. Uchneat, of GardenGenetics LLC, in Bellefonte, Pennsylvania, USA. It originated from a controlled cross conducted in October 2012, between the proprietary breeding line designated '3169-1-5M-2', as the female parent, and the proprietary breeding line designated '3169-1-5M-1', as the male parent. From the resulting progeny, 'G13518' was selected for its vigorous, upright and freely branching plant growth habit, dark green to bronze colour and appearance of foliage, free flowering habit, flower colour, and flower size. 'G13518' was first propagated by terminal cuttings, in August 2013, in Bellefonte, Pennsylvania, USA.

Tests & Trials: The comparative trial for 'G13518' was conducted in a polyhouse during the spring of 2016 at BioFlora Inc., in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15.0 cm pots on April 15, 2016. The observations and measurements were taken from 10 plants, or parts of plants, of each variety on May 25, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
