Origin & Breeding History: 'HORCOGJIL' originated from a controlled cross made between the female parent, an unnamed seedling derived from the cross 'Laura Ford' x 'Goldbusch', and the male parent 'Horjilly', in June 2000 in Stansted, Essex, United Kingdom. It was bred and developed by the breeder Heather Horner. From the resulting progeny, 'HORCOGJIL' was selected in July 2001 based on its plant growth habit, good fragrance, apricot-orange flower colour and strong disease resistance. 'HORCOGJIL' was first propagated through grafting and softwood cuttings in July 2001 in Stansted, Essex, United Kingdom.

Tests & Trials: The comparative trial for 'HORCOGJIL' was conducted in an outdoor irrigated container trial during the spring and summer of 2016 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 12 plants each of the candidate variety and reference variety. All plants were grown from 10 cm liners and transplanted into 7.5 litre containers on July 16, 2015. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on May 16, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
