Origin & Breeding History: The variety 'Minredda' originated from an open pollination between two unknown parents, in July 2003 at Morgan Hill, California, USA. Seed from a single plant was collected and sown in a greenhouse in Gilroy, california in February 2004. A single plant was selected from the progeny in August 2004, based on criteria including non-sticky leaves, plant growth habit, branching characteristics, early flowering, flower size and novel flower colour.

Tests & Trials: Trials for 'Minredda' were conducted in a polyhouse during the spring of 2011, in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 15 cm pots on April 25, 2011. Observations and measurements were taken from 10 plants of each variety on June 13, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
