The lateral margin of the ray floret is slightly involute and the tip is rounded with a dentate tip.

Origin & Breeding History: 'Melody Bolero' originated from a hybridization made in a controlled breeding program during 1996 at Lisse, The Netherlands. The female parent was 'Gallery Singer' and the male parent was an unknown Dahlia cultivar. The initial selection was made in September 1997. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: Tests and trials for 'Melody Bolero' were conducted in a polyhouse during the spring/summer of 2005 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings, transplanted into 15 cm pots on April 28, 2005. Observations and measurements were taken from 10 plants of each variety on June 14, 2005. All colour measurements were made using the 2001 RHS Colour Chart.
