Origin & Breeding History: The variety 'Navy Lady' originated from a controlled cross made at the Agriculture and Agri-Food Canada Research Station in Saint-Jean-sur-Richelieu, Québec in 2003. The female parent was the variety 'Fourth of July' and the male parent was the variety 'Astrid Lindgren'. The achenes from the ripe fruit were harvested and germinated in the greenhouse facilities at St-Jean-sur-Richelieu, Québec. The seedlings were planted in the greenhouse 3 to 5 months prior to being planted in the field at the Agriculture and Agri-Food Canada L'Acadie Experimental Farm in Quebec. The seedling population was subjected to several rounds of selection between 2004 and 2008 for hardiness, growth form, foliage colour and flower colour. 'Navy Lady' (experimental designation SJ03H003-02) was selected from this population.

Tests & Trials: Tests and trials for 'Navy Lady' were conducted an outdoor trial in St. Catherines, Ontario in 2010. The trial included 7 plants of the candidate variety and 10 plants of the reference variety. Plants were spaced 30 cm apart.
