Origin & Breeding History: 'Takfoplgo' originated from a cross conducted by the breeder during a controlled breeding program in Honselersdijk, the Netherlands in June 2008. The cross involved the proprietary Digitalis purpurea breeding selection '8044-1' as the female parent and the proprietary Digitalis canariensis breeding selection '7738' as the male parent. 'Takfoplgo' was initially selected in June 2009 for its unique flower colouration.

Tests & Trials: The comparative trial for 'Takfoplgo' was conducted in a polyhouse during the summer of 2015 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings transplanted into 20 cm standard pots on June 18, 2015. The observations and measurements were taken from 10 plants, or parts of plants, of each variety on July 29, 2015. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
