Origin & Breeding History: 'Little Vision in Purple' originated from hybridization work conducted during the summer of 2004 between Astilbe varieties 'Vision' and 'Spartan'. 'Little Vision in Purple' was selected during the summer of 2006. The initial selection criteria included low plant growth habit, flower colour and foliage colour.

Tests & Trials: The comparative trial of 'Little Vision in Purple' was conducted outdoors under a shade cloth during the summer of 2014 at Variety Rights Management in Oxford Station, Ontario. It included a total of 12 plants of the candidate variety and 15 plants of the reference variety. Each plant was grown in a 20 cm diameter pot and the pots were spaced 30 cm apart. Observations and measurements were taken from 10 plants or parts of plants of each variety. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
