Origin & Breeding History: 'Delilah' was discovered and selected in the nursery of the breeder, Mr. H.G. Oudshoorn in Rijpwetering, the Netherlands, in 1999. Its parentage was the Phlox paniculata variety 'Lizzy' x P. paniculata 'Rowie' and the original cross was performed in 1998. The objective of the breeding program was to create new Phlox varieties with improved form as well as improved floral traits.

Tests & Trials: Trials for 'Delilah' were conducted during the summer of 2008 at Oxford Station, Ontario. The trials consisted of 15 plants of each variety, grown in 15cm pots in a polyhouse. The plants were spaced approximately 45 cm apart. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
