Origin & Breeding History: 'PIIVAC-II' originated from an open pollinated cross that occurred in 2011 between an unnamed seedling, as the female parent, derived from seed collected from Vitex variety 'PIIVAC-I', and an unknown male parent in Watkinsville, Georgia, USA. From the resulting progeny, 'PIIVAC-II' was selected based on its compact and mounding plant growth habit, foliage colour, flower colour and flower abundance. 'PIIVAC-II' was first asexually propagated by softwood cuttings in 2011 in Watkinsville, Georgia, USA.
Tests & Trials: The comparative trial for 'PIIVAC-II' was conducted outdoors during the spring and summer of 2017 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 10 plants each of the candidate and reference variety. All plants were grown from 6 cm rooted liners that were each planted in a 7.5 litre container. Observations and measurements were taken from 10 plants or parts of plants of each variety on August 23, 2017. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
