Asexual reproduction by vegetative tip cuttings was first conducted in Fort Myers, Florida in March 2007.

Tests & Trials: Trials for 'Bold Yonew York' were conducted in a greenhouse trial during the Fall of 2011 in Niagara-on-the-Lake, Ontario. On August 8, 2011, fifty unrooted cuttings were directly stuck into 15 cm pots, with 5 cuttings per pot. The trial included a total of 10 pots of each variety spaced 30 cm apart. Plants were pinched once prior to short day treatment. Observations and measurements were taken from 10 plants of each variety on November 8, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
