Origin & Breeding History: 'Nemhawit' was developed by the breeder, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. The variety originated from a controlled cross made in August 1999 in Enkhuizen, between the female parent 'A233-1' and the male parent 'A71-2'. A plant was selected from the progeny in May 2000. The selected plant was selfed for two generations (2000, 2001). The new variety was selected in May 2002 based on criteria for early flowering, flower shape and colour. Asexual reproduction of the new variety by vegetative cuttings was first conducted in June 2002.

Tests & Trials: The tests and trials for 'Nemhawit' were conducted in a greenhouse at BioFlora Inc. in St. Thomas, Ontario during the spring of 2006. The trial included 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on March 31, 2006. Observations and measurements were taken from 10 plants per variety on May 9, 2006. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) Colour Chart.
