ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Alpine Dianthus and will be referred to hereafter as ‘Spangled Star’. Alpine Dianthus are of hybrid origin and are hardy perennials grown for landscape use.
The new Dianthus resulted from a breeding program conducted by the inventor in Dawlish, Devon, England. The breeding project that resulted in the selection of ‘Spangled Star’, began in 1992 after growing and evaluating over 80 varieties of Dianthus. ‘Spangled Star’ was selected as a single plant amongst a unique group of Dianthus in the breeding program, “The Clock Series”, so named for the unique color patterns of their flowers. ‘Spangled Star’ was selected as a single plant in 1994 by the inventor from seedlings that resulted from open crosses and back crosses made using an old variety, ‘Queen of Henri’ (unpatented), which is of hybrid origin.
‘Spangled Star’ was selected for its unique flower color combined with other desirable characteristics. The new variety of Dianthus is unique in having fragrant, red flowers with two distinct pale pink blotches on each petal with a pale pink throat and margins. It has a profuse flowering habit with 3-5 flowers per stem opening in succession. ‘Spangled Star’ can be further characterized by its compact habit; having freely branching upright shoots resulting in a neat mound of grey-green foliage. The new invention, ‘Spangled Star’, is unlike any other Dianthus known to the inventor. The closest comparison varieties are others that have arisen from the breeding program but have flowers with completely different color patterns. The antecedent variety, ‘Queen of Henri’ (unpatented), has a similar pattern to the flowers but the flower color is maroon as opposed to red, it is a taller plant, and has a shorter bloom period in comparision to ‘Spangled Star’.
Asexual reproduction of the new cultivar was first accomplished by taking shoot cuttings in Dawlish, Devon, England in 1994 by the inventor. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish this cultivar from other commercial varieties. ‘Spangled Star’ has not be tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions:
1. The flowers of ‘Spangled Star’ are red with two pale pink blotches and a pale pink, serrated margin on each petal and a pale pink throat. The flowers have a clove fragrance.
2. ‘Spangled Star’ has a compact growth habit; it is freely branched and has a reduced height in comparision to the parent variety, ‘Queen of Henri’ (unpatented).
3. The foliage of ‘Spangled Star’ is grey-green and glaucous.
4. ‘Spangled Star’ has an extended bloom period in comparision to its parent and blooms in profusion in June and July with 3-5 flowers per stem opening in succession.
5. ‘Spangled Star’ is hardy at least to USDA Zone 5.
