Description

CROSS-REFERENCES TO RELATED APPLICATIONS
The application for this new invention will be co-pending with another application corresponding to a plant that was derived from the same breeding program; entitled Dianthus Plant Named ‘Pixie Star’, Ser. No. 09/633,301.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Alpine Dianthus and will be referred to hereafter as ‘Brilliant 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 the “Star Series” of Alpine Dianthus began in 1992 after growing and evaluating over 80 varieties of Dianthus. The primary focus of the breeding program is to select alpine type Dianthus in a range of unique flower colors that do not require vernalization for flowering and exhibited a compact plant habit with short flower stems. ‘Brilliant Star’ was selected as a single plant that resulted from crossing the cultivar ‘Whatfield Cyclops’ (unpatented) as the seed parent with an unnamed Dianthus plant as the pollen parent.
‘Brilliant Star’ was selected for it's unique flower color combined with other describe characteristics. The new variety of Dianthus can be characterized by it's double, white flowers with dark magenta centers combined with a compact plant habit, dark green, glaucous foliage, a perpetual flowering habit and a day neutral flowering response. The new invention is unlike any other Dianthus that is known to the inventor. It is similar to the co-pending variety ‘Pixie Star’ in its perpetual flowering habit and the ability to flower without vernalization, however differs in other characteristics including flower color. ‘Brilliant Star’ differs from the seed parent, ‘Whatfield Cyclops’ (unpatented), in having white petals with a dark eye, a more compact habit, a perpetual blooming habit and a day neutral flowering response. ‘Whatfield Cyclops’ (unpatented) has flowers that are bright magenta with a dark magenta eye. The new invention is most similar to the cultivar ‘Spring Star’ (unpatented) in overall characteristics, however, ‘Brilliant Star’ is more compact and ‘Spring Star’ (unpatented) has light magenta colored blooms.
Asexual reproduction of the new cultivar was first accomplished by taking shoot cuttings in Dawlish, Devon, England in 1997 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. ‘Brilliant 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 ‘Brilliant Star’ are double and white a dark magenta eye zone.
2. ‘Brilliant Star’ has a compact growth habit.
3. The foliage of ‘Brilliant Star’ is dark green and glaucous.
4. ‘Brilliant Star’ is perpetual blooming.
5. ‘Brilliant Star’ is day neutral and does not require vernalization to initiate flowers.
6. ‘Brilliant Star’ is hardy at least to USDA Zone 5.
BRIEF DESCRIPTION OF THE DRAWING
The first drawing is of Dianthus ‘Brilliant Star’ and shows the plant and habit when in bloom.
The second drawing shows a close-up of the flowers of ‘Brilliant Star’. All photographs were taken in May and are of plants grown in one-gallon containers in Encinitas, Calif. The colors in these photographs are as accurate as possible by conventional photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new cultivar as grown in a one-gallon container under greenhouse conditions in Encinitas, Calif. The observed plant had been produced from shoot cuttings taken in the previous summer to the date of observation in May 2000. The plant had been overwintered at a night minimum temperature of 65 degrees Fahrenheit with day venting at 75 degrees Fahrenheit. The greenhouse was lightly shaded to an approximate light intensity of 5000 foot-candles. Day length was as naturally occurring in Southern California, approximately 13 hours during the month prior to flowering and observation. The color determination is in accordance with The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
