Origin & Breeding History: 'Balazvio' originated from a controlled breeding program on February 1, 2003, at Arroyo Grande, California. The female parent was the proprietary verbena selection designated BFP-2256, characterized by its lavender flower colour, medium green leaf colour, and semi-trailing growth habit. The male parent was the verbena 'Lan Roypur' (Lanai™ Royal Purple), characterized by its dark purple flower colour, dark green leaves and mounded, trailing growth habit. The initial selection was made on May 19, 2003. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: The trials for 'Balazvio' were conducted in a polyhouse during the spring/summer of 2006 at BioFlora Inc., in St. Thomas, Ontario. The trials consisted of a total of 15 plants of each variety. All plants were grown from rooted cuttings, transplanted into 11 cm pots on April 18, 2006. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 17-22, 2006. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
