Origin & Breeding History: 'Seki Blahrt' was developed by the breeder, Jason Jandrew, an employee of Goldsmith Seeds, Inc., in Gilroy, California, U.S.A. as part of a planned breeding program. It originated from a hybrid cross conducted in October 2006 between the female parent variety 'Sweet Caroline Purple' and the male parent variety 'Sweet Caroline Sweetheart Purple'. The resultant seed was sown in a greenhouse in December 2006. In March 2007, a single plant from the progeny was selected by the breeder based on its foliage quality, foliage colour and plant growth habit.
Tests & Trials: The trial of 'Seki Blahrt' was conducted in a polyhouse during the summer of 2009 at BioFlora Inc. in St. Thomas, Ontario. It included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on May 28, 2009. Most observations and measurements were taken from 10 plants or parts of plants of each variety on July 3, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
