Origin & Breeding History: 'Miss Violet' originated from a controlled cross conducted at North Carolina State University in Raleigh, North Carolina, USA, in July 2009. The cross was made between the female parent variety 'Blue Chip' and the male parent variety 'Miss Molly'. The new variety was selected in July 2010 in Jackson Springs, North Carolina based on its low fertility, growth habit, flower colour and fragrance. Asexual propagation by softwood and semi-hardwood stem cuttings of 'Miss Violet' was first conducted in October 2010 in Raleigh, North Carolina, USA.

Tests & Trials: The comparative trial for 'Miss Violet' was conducted in an outdoor irrigated container trial during the summer of 2017, at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 12 plants each of the candidate and reference variety. All plants were grown from 10 cm rooted liners and transplanted into 9 litre containers on July 15, 2017. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety on August 27, 2017. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
