The new variety was discovered as a chance seeding in a nursery block of un-named Echinacea purpurea plants that had been allowed to set seed in 2003. 'Virgin' was selected based on improved form and floral traits.

Tests & Trials: Trials for 'Virgin' were conducted during the summer of 2009, in Oxford Station, Ontario. Fifteen plants each of the candidate and reference varieties were grown in 15 cm pots spaced 60 cm apart in a polyhouse. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
