Origin & Breeding History: 'Balserdalav' was developed by Ball Horticultural Company in Arroyo, California and originated from an open pollination of the osteospermum variety 'Balserpurp' (Serenity Purple) in 2003. The initial selection was made in December 2003. Asexual propagation since that time has been through vegetative cuttings.

Tests & Trials: The trials for 'Balserdalav' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2006. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
