Origin & Breeding History: 'Spangled Star' originated from a breeding program which was conducted by John Whetman in Dawlish, Devon, England. The primary focus of this breeding program was to select alpine type Dianthus in a range of unique flower colour patterns. The program began in 1992 after growing and evaluating 80 varieties of Dianthus. 'Spangled Star' was the result of open crosses and back crosses made using an old variety, 'Queen of Henri'. It was selected based on its fragrant flowers, flower and foliage colour, flowering habit and plant growth habit.
Tests & Trials: The test and trial for 'Spangled Star' was conducted in a polyhouse during the summer of 2005 at Variety Rights Management in Oxford Station, Ontario. The trial included 10 plants of each variety. The plants were grown in 15 cm pots spaced 25 cm apart. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten plant measurements.
