Origin & Breeding History: The variety 'AKIV98-01' originated from a controlled cross made in Higashiomi, Shiga, Japan on May 25, 2005. The female parent was the variety 'Sunvivaro' and the male parent was the variety 'USBENAL17'. The new verbena was selected as a single plant from the resultant progeny on June 29, 2007 in Higashiomi, Shiga, Japan and was selected based on flower colour, flower size and good resistance to powdery mildew. The variety was first propagated by vegetative cuttings on December 30, 2007 in Bonsall, California, USA.
Tests & Trials: Trials for 'AKIV98-01' were conducted in a polyhouse during the spring of 2010, 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 11 cm pots on May 4, 2010. Observations and measurements were taken from 10 plants of each variety on June 4, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
