Origin & Breeding History: The variety 'Balserlem' originated from a self pollination conducted in June 2006 at Santa Paula, California, USA. The female parent was a proprietary breeding selection designated 10925-1, characterized by its bright yellow flower colour, medium green foliage colour and upright growth habit. The initial selection was made in February 2007 and asexual propagation since that time has been through the use of vegetative cuttings. The variety was selected for its yellow flower colour and compact well branched growth habit.
Tests & Trials: Trials for 'Balserlem' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of fifteen plants of the candidate and reference varieties. Rooted cuttings were transplanted into 11 cm pots on April 28, 2010. Observations and measurements were taken from ten plants or parts of plants on June 15, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
