Origin & Breeding History: 'ROBPWCHP' is a product of a planned breeding program developed by the plant breeder, Robert J. Roberson, in Grain Valley, Missouri, U.S.A. It originated from a cross made in August 2002 between the female parent variety 'Patriot Cowboy' and the male parent variety 'Patriot Honey Love'. 'ROBPWCHP' was selected from the resultant progeny in May 2003 based on its flower colour, low seed set, uniform plant growth habit and good plant vigour.

Tests & Trials: Trials for 'ROBPWCHP' 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 cutthings 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.
