Origin & Breeding History: 'BID719' originated from a controlled cross between the female parent plant Bidens triplinervia and the male parent variety 'Peters Goldteppich'. The new Bidens was bred and developed by the breeder, Thomas Psenner, with Plant Point GmbH, in Bolzano, Italy in 2007. A single plant from the resultant seedlings was selected in August 2007 in Bolzano, Italy, based on flower type, plant habit, leaf size and leaf colour. Asexual reproduction by cuttings was first conducted in November 2007 in Bolzano, Italy.

Tests & Trials: Trials for 'BID719' were conducted in a polyhouse during the spring of 2011 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference variety. Rooted cuttings were transplanted into 11 cm pots on April 29, 2011. Observations and measurements were taken from 10 plants of each variety on June 14, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
