The female parent was a proprietary seedling designated 07V424-03 and the male parent was an unnamed seedling selected from the seed variety 'Nioimurasaki'. The new verbena was selected as a single plant from the resultant progeny on June 11, 2008, in Bonsall, California, USA. The variety was selected based on criteria for good branching characteristics, plant growth habit and disease resistance. The variety was first propagated by vegetative cuttings on June 12, 2008 in Bonsall, California, USA.
Tests & Trials: Trials for 'AKIV571-1' were conducted in a polyhouse during the summer of 2011, in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm shallow pots on May 2, 2011. Observations and measurements were taken from 10 plants of each variety on June 23, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
