Variety used for comparison: 'Nemhapri' (Magma Flame Pink)

Summary: The upper lobes of 'Organza' are light yellow orange fading to light yellow with age while 'Nemhapri' is light yellow orange in the background only. 'Organza' has dark violet markings on the upper lobes while they are purple for 'Nemhapri'. The lower lip of 'Organza' is yellow orange while it is light yellow orange for 'Nemhapri'. The secondary colour developing in the veins of the lower lip of 'Organza' is purple red while it is purple red to blue pink in the veins for 'Nemhapri'. As the corolla ages, the colour intensifies for 'Organza' while it weakly fades for 'Nemhapri'.

Origin & Breeding History: 'Organza' originated from a controlled cross made in August 2002 in Enkhuizen, The Netherlands. The female parent was identified as D0366-2 and the male parent was identified as B0112-1. The new Nemesia variety was selected from the resultant progeny as a single plant in May 2003 based on criteria for earliness, plant form, and sterility. Asexual reproduction by vegetative cuttings was first conducted in July 2003 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 15, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) colour chart.
