Origin & Breeding History: 'Nemimblu' originated from a self-pollination of the Nemesia frutescens plant identified as C0072-1 occurring in August 2000 in Enkhuizen, The Netherlands. The new Nemesia variety was selected from the resultant progeny as a single plant in May 2001 based on criteria for earliness, plant form, and sterility. Asexual reproduction by vegetative cuttings was first conducted in July 2001 in Enkhuizen, The Netherlands.

Tests & Trials: The PBR trials were conducted in a polyhouse during the spring of 2007 in St. Thomas, Ontario. The trials included a total of 15 plants of the candidate variety and reference variety. All plants were grown from rooted cuttings and transplanted into 10.5 cm pots on March 20, 2007. Observations and measurements were taken from 10 plants of each variety on May 16, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) colour chart.
