Origin & Breeding History: 'Meigalpio' originated from hybridization work conducted by the breeder at Le Luc en Provence, France in June 1997. The cross was conducted between the female unnamed proprietary seedling ('The Fairy' x 'Kormax') and the male unnamed proprietary seedling (an unnamed proprietary seedling x 'Morpapplay'). In September 2005, 'Meigalpio' was selected based on its improved attractive flower colours, spreading ground cover growth habit and attractive foliage.

Tests & Trials: Trials for 'Meigalpio' were conducted in an outdoor container trial and then moved indoors during the summer of 2013 at Variety Rights Management, Oxford Station, Ontario. The trial consisted of a total of 9 plants of the candidate variety and 8 plants of the reference variety. All plants were grown from bare-rooted plants and transplanted into 22 cm pots, spaced 45 cm apart. Observations and measurements were taken from 10 plants of each variety in June 2013. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
