Origin & Breeding History: 'Lan Upbriro' originated from a hybrid cross in August 2005 between the female parent variety 'Lanai Upright Magenta' and the male parent variety 'Lanai Upright Violet'. The new verbena was bred and developed by the breeder Michell Hanes, in Gilroy, California as part of a planned breeding program. The resultant seed from the cross was sown in a greenhouse in November 2005. In February 2006 a single plant was selected by the breeder based on flower colour and plant growth habit.

Tests & Trials: Trials for 'Lan Upbriro' were conducted in a polyhouse during the spring of 2009, in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 11 cm pots on May 6, 2009. Observations and measurements were taken from 10 plants of each variety on June 2, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
