Origin & Breeding History: 'Power Red' originated as a naturally occurring mutation of the variety 'Power Purple' discovered on October 21, 2010 at Willy's Greenhouses Ltd. in Niagara on the Lake, Ontario. The parent plant was put into 24 hour lighting to initiate vegetative growth. A series of stem cuttings were made to determine whether this mutation was stable and true to type. The new variety was selected in 2011 after observing its performance in all four seasons crop cycles. The selection of 'Power Red' and the objectives of the breeding program were based on selecting plants with flower colour that would perform well in year round production.

Tests & Trials: Trials for 'Power Red' were conducted at Willy's Greenhouses Ltd., in Niagara on the Lake, Ontario in the fall of 2012. The trial consisted of 25 pots of each variety with 3 plants per pot. The pots were approximately 12.7 cm in diameter and were spaced 20 cm apart. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
