Origin & Breeding History: 'G13525' was bred and developed by the breeder, Michael S. Uchneat, of GardenGenetics LLC, in Bellefonte, Pennsylvania, USA. It originated from an open pollinated cross conducted in October 2012 between the proprietary breeding line designated '3169-1-5M-6', as the female parent, and a pool of six proprietary breeding lines designated '3180-5M-1', '3180-5M-2', '3180-5M-3', '3180-5M-4', '3180-5M-5', and '3180-5M-7', as the male parent. From the resulting progeny, 'G13525' was selected in July 2013 for its vigorous upright growth habit, freely branching and flowering habit, colour and appearance of foliage, flower colour, and flower size. 'G13525' was first propagated asexually using terminal cuttings, in August 2013, in Bellefonte, Pennsylvania, USA.

Tests & Trials: The comparative trial of 'G13525' was conducted in a polyhouse during the spring of 2017 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 cm pots on April 14, 2017. Unless otherwise indicated, the observations and measurements were taken from 10 plants or 10 parts of plants of each variety on June 6, 2017. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
