Asexual propagation since its selection has been through vegetative cuttings.

Tests & Trials: Trials for 'Balserdarp' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario.

Observations and measurements were taken from 10 plants of each variety on June 1, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
