Origin & Breeding History: 'Balwatazmi' originated from the open pollination of proprietary Lobelia breeding selection designated LOB-133, conducted during August 2002 at Arroyo Grande, California, USA. LOB-133 is characterized by its' lavender-blue and white flower color, dark green leaf color, and upright growth habit. The initial selection was made on January 28, 2003. Asexual propagation since that time has been through the use of vegetative cuttings. 'Balwatazmi' was selected for its flower colour pattern.

Tests & Trials: Tests and trials were conducted in the summer of 2007 in a polyhouse in St. Thomas, Ontario. Trials consisted of 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 11cm pots on April 23, 2007. Observations and measurements were taken from 10 plants of each variety on June 25, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
