From the resulting progeny, 'USTUN87002' was selected as a single seedling on June 10, 2015 based on its plant growth habit, plant vigour, small flower size and flower colour. 'USTUN87002' was first propagated by vegetative tip cuttings on June 11, 2015 in Bonsall, California, USA.
Tests & Trials: The comparative trial for 'USTUN87002' was conducted in a polyhouse during the spring of 2019 at BioFlora, Inc. in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 8, 2019. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on May 21, 2019. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
