Origin & Breeding History: 'Indiglo Girl' originated from a cross conducted by the breeder in the summer of 2013 in Zeeland, Michigan, USA. The cross was made between the female parent, a proprietary unnamed hybrid designated as 12-31-02 and the male parent variety 'Violet Riot'. Seeds from the cross were harvested in the fall of 2013 and sown at Walters Gardens, Inc., in Zeeland, Michigan, USA. Initial selection of 'Indiglo Girl' was made in the spring of 2014 based on distinct and compact habit. Asexual propagation by basal cuttings was first conducted in 2014.

Tests & Trials: The comparative trial for 'Indiglo Girl' was conducted during the summer of 2022 at Variety Rights Management in Oxford Station, Ontario. The trial consisted of 10 plants each of the candidate and reference varieties, each individually grown in 16 cm pots. Pots were spaced approximately 45 cm apart. Observations and measurements were taken from 10 plants or parts of 10 plants of each variety. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
