Origin & Breeding History: 'Petersurpr' was the result of a breeding program conducted by the breeder, Peter Wicki, in Gensingen, Germany. The objectives of the breeding program were to create new Bidens varieties with a spreading and compact growth habit and adapted for use in container gardening. 'Petersurpr' originated from an open-pollinated cross of Bidens variety 'Golden Mega Star' conducted in the early spring of 2001 in Germany. It was selected in the summer of 2001 based on large flower size, early flowering, longer flowering period and compact bushy plant growth habit.
Tests & Trials: The test and trial for 'Petersurpr' was conducted in a poly-house during the summer of 2006 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots on May 26, 2006. Observations and measurements were taken from 10 plants of each variety from June 26, 2006. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
