Origin & Breeding History: 'Jade Peacock' originated from a cross pollination that occurred on March 8, 2011 between the variety 'Pink Brushes', as the female parent, and the variety 'Cascade Creeper', as the male parent. The resulting seeds were harvested on April 6, 2011. 'Jade Peacock' was selected during the late summer of 2011 based on improved foliage colour, flower performance and landscape usefulness. All breeding work was conducted at Walters Gardens Inc., Zeeland, Michigan, USA.

Tests & Trials: The comparative trial for 'Jade Peacock' was conducted in a polyhouse during the spring of 2015 at Variety Rights Management in Oxford Station, Ontario. There were 13 plants of the candidate variety and 15 plants of the reference variety. Each plant was grown in a 16 cm diameter pot, one plant per pot with 45 cm spacing between the pots. Observations and measurements were taken from 10 plants or parts of plants of 'Jade Peacock' and 'Sugar and Spice'. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
