Origin & Breeding History: 'Violet Riot' originated from an open pollinated cross between the Savia nemerosa variety 'May Night' as the female parent and an unknown male parent during the summer 2012. The resulting seeds were sown later in the summer of 2012 and 'Violet Riot' was selected for its purple flower colour and compact growth habit. The breeding and selection work were conducted in Zeeland, Michigan, USA.

Tests & Trials: The comparative trial for 'Violet Riot' was conducted in a polyhouse during the spring of 2015 at Variety Rights Management in Oxford Station, Ontario. There were 15 plants of the candidate variety and 18 plants of the reference variety. Each plant was grown in a 16 cm diameter pot, one plant per pot with 45 cm spacing between the pots. In most cases observations and measurements were taken from 10 plants or parts of plants each of the candidate and reference variety. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
