Origin & Breeding History: 'PAST0517E' originated from an open pollinated cross between a group of Gomphrena puchella proprietary selections occurring in September 2013, in Santa Paula California. Resulting seed from the cross was field planted and 'PAST0517E' was selected, as a single plant, in July 2014 based on duration of flowering and growth habit.

Tests & Trials: The comparative trial for 'PAST0517E' was conducted in a polyhouse, during the spring and summer of 2019, at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm containers on June 12, 2019. The observations and measurements were taken from 10 plants, or parts of plants, each of the candidate and reference variety, on July 15, 2019. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
