Origin & Breeding History: 'Penharcar' was developed through inbred breeding of the variety 'Gigant'. One cycle of half-sib selection between June 2002 through to October 2002 was conducted in Enkhuizen, the Netherlands. Seeds from the selection were sown in January 2003. A single seedling was selected based on criteria including compact growth habit, branching and time of flowering. Asexual reproduction by cutting was first conducted in August 2003 in Enkhuizen, the Netherlands.
Tests & Trials: The comparative test and trial of 'Penharcar' was conducted in a polyhouse during the spring-summer of 2008 at Bioflora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 20 cm pots on May 15, 2008 . Observations and measurements were taken from 10 plants of each variety on July 18, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
