Origin & Breeding History: 'Marsha' originated as a chance seedling at Kwekerij De Bloezem in Reeuwijk, The Netherlands in 1996. It is suspected that the female parent was the variety 'Royal Blue' due to its proximity to the new variety in the trial. 'Marsha' was initially selected for its growth habit and flower colour.
Tests & Trials: Trials for 'Marsha' were conducted in an outdoor trial during the summer of 2012 in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and 8 plants of the reference variety. All plants were grown from bare-rooted plants, planted into 11 cm pots in April 2011 and transplanted to an outdoor bed on September 17, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
