Origin & Breeding History: 'Sunmaricoho' was bred during the period of September to October 2006 in an isolated area of the Omi Research and Development Center of Suntory Flowers Ltd., in Higashiomi-shi, Shiga, Japan. The objective of this breeding was to create new Verbena varieties with compact, upright and mounding growth habit, abundant branching, and white flowers. 'Sunmaricoho' originated from a controlled cross pollination between the proprietary varieties 'VW416' as the female parent and '02H-11-2' as the male parent. The resulting seeds were germinated, grown to maturity, and in October 2007, one plant was selected for its growth habit and flower colour. This selected plant was propagated by cuttings and grown in trials from April to November 2009 to examine its botanical characteristics. It was later named 'Sunmaricoho'.

Tests & Trials: The comparative trial of 'Sunmaricoho' was conducted in a polyhouse during the spring of 2014 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings which were transplanted into 15.2 cm shallow pots on April 23, 2014. Observations and measurements were taken from 10 plants of each variety on June 3, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
