Origin & Breeding History: 'ROBPWPUR' is a product of a planned breeding program developed by the plant breeder, Robert J. Roberson, in Grain Valley, Missouri, U.S.A. It was discovered in July 2002 as a naturally occuring branch mutation of Lantana montevidensis variety 'Alba'. 'ROBPWPUR' was selected based on its flower colour, foliage colour, trailing plant growth habit and production characteristics.
Tests & Trials: Trials for 'ROBPWPUR' were conducted during the spring of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 13, 2008. Measured characteristics were based on measurements taken from 10 plants or parts of plants of each variety on July 4, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
