Origin & Breeding History: 'Neon Star' is the product of a breeding program which was established in 1969 in Houndspool, Dawlish, Devon, United Kingdom the focus of which was to produce dwarf varieties with a wide range of bright coloured perfume scented flowers with a long flowering season. 'Neon Star' was produced by induced hybridization in 1996 of the female parent 'Brehemen' and an unidentified male dianthus parent. It was selected in 1997 based on its intense magenta flower colour, compact habit and long flowering season.

Tests & Trials: Tests and trials were conducted in a polyhouse at Oxford Station, Ontario during the summer 2005. Plants were individually grown in 15cm plastic pots with a pot spacing of 30cm.
