Origin & Breeding History: 'Lundy' originated from an open pollinated cross between the female parent variety 'Hopleys Orange' and pollen from an unknown male parent in the summer of 1999 in Grand Haven, Michigan, USA. The new variety was bred and developed by the breeder, Timothy D. Wood in Grand Haven. 'Lundy' was selected in the summer of 2006 based on flower colour, flower size, branching density, attractive foliage and repeat blooming. Asexual reproduction of the variety was first conducted by softwood cuttings in July 2006 in Grand Haven, Michigan, USA.

Tests & Trials: Trials for 'Lundy' were conducted in an outdoor trial during the summer of 2013 in St. Thomas, Ontario. The trial included 12 plants each of the candidate and reference variety. Plants were grown from rooted cuttings and transplanted into 7.6 litre containers in May 2013. Observations and measurements were taken from 10 plants of each variety on September 27, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
