Origin & Breeding History: 'Lilac Chip' was bred and developed by the breeders at North Carolina State University in Raleigh, North Carolina, USA. It originated from a controlled cross conducted during the summer of 2005 between the variety 'Blue Chip' as the female parent and the variety 'Miss Molly' as the male parent. The resultant seedlings were planted in field trials in the spring of 2006 in Jackson Springs, North Carolina. 'Lilac Chip' was selected in August 2006 based on its very compact growth habit, dense branching, lilac coloured flowers, inflorescence of intermediate size, and small amount of seed set when grown in the field. The first asexual propagation of 'Lilac Chip' was conducted in August 2006 in Raleigh, North Carolina.

Tests & Trials: The PBR trial for 'Lilac Chip' was conducted outdoors during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants each of candidate and reference varieties. All plants were grown from 11.5 cm rooted liners and transplanted into 13.5 litre containers on July 8, 2011. Observations and measurements were taken from 10 plants of each variety on July 4, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Charts.
