Origin & Breeding History: 'Kerlatte' originated from an open pollinated cross that occurred in August 2011 in Cambridge, United Kingdom, as part of a planned breeding program. The female parent was a proprietary breeding selection designated '10-423-01', and the male parent was unknown. The initial selection was made in May 2012 based on plant growth habit, flower and vein colour, flower size, flowering time and garden performance. 'Kerlatte' was first propagated by vegetative tip cuttings in September 2012, in Cambridge, United Kingdom.

Tests & Trials: The comparative trial for 'Kerlatte' was conducted in a polyhouse during the spring of 2016 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 17, 2016. Observations and measurements were taken from 10 plants or parts of plants of each variety on May 17, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
