Origin & Breeding History: 'Balcabwitim' originated from a cross conducted during November 2002, in Elburn, Illinois, USA. The female parent was the proprietary Calibrachoa breeding selection designated as '1023-2' and the male parent was from a pollen mix of the designations '1015-1m-1a', '1015-1m-3b', '1031-3', '1032-4B', '1036-1', '2045-6', '2049-1', '2057-1', '2058-1', '2058-5', '2061-1' and '2074-1a'. The initial selection of 'Balcabwitim' was made on June 3, 2004 based on its branching habit, time of flowering, flower colour and semi-upright to prostrate growth habit. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: Trials for 'Balcabwitim' were conducted during the summer of 2007, in a polyhouse, in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 1, 2007. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety (except for plant height where 5 plants were measured) on July 3, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
