Origin & Breeding History: 'Balcinsu' originated from a cross pollination conducted in January 2004, at Dulce Nombre de Cartago in Costa Rica, as part of a controlled breeding program. The female parent was variety 'Elfers' characterized by its deep purple, green and magenta foliage and upright plant growth habit. The male parent was a bulk pollen mix of Wizard varieties characterized by their green, red, magenta, yellow green and scarlet foliage, zoned and solid foliage colour patterns and upright plant growth habit. 'Balcinsu' was selected on November 18, 2004 based on its vigour, foliage colour and plant growth habit.

Tests & Trials: Trials for 'Balcinsu' were conducted during the summer of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on August 12, 2008. Measured characteristics were based on measurements taken from 10 plants or parts of plants on September 17, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
