Origin & Breeding History: 'Balarwite' originated from a cross conducted on August 15, 2002 between the female parent, Nemesia selection 'NCT-2562' characterized by its white flowers, medium green leaves and compact, upright growth habit and an unidentified male parent. This cross was part of a controlled breeding program which took place in Arroyo, California, U.S.A. The initial selection of 'Balarwite' was made on November 20, 2002.

Tests & Trials: The tests and trials for 'Balarwite' 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 of each variety on May 5, 2006. All colour characteristics were determined using the 2001 Royal Horticultural society (RHS) colour chart.
