Genus and species: Chaenomeles speciosa.
Variety denomination: ‘Pink Storm’.
BACKGROUND OF THE INVENTIONThe present invention comprises a new and distinct cultivar of flowering quince, botanically known as Chaenomeles speciosa, and hereinafter referred to by the cultivar name ‘Pink Storm’. This new flowering quince was developed through a breeding program at North Carolina State University, Mills River, N.C. ‘Pink Storm’ is an F1 hybrid between the female parent, Chaenomeles speciosa ‘Spitfire’ (unpatented) and the male parent, Chaenomeles speciosa ‘Dragons Blood’ (unpatented). The first asexual propagation of ‘Pink Storm’ was carried out in June 2003 by rooting stem cuttings at the North Carolina State University, Mountain Horticultural Crops Research Station, Mills River, N.C. and has been asexually reproduced repeatedly by vegetative cuttings in North Carolina over a five year period.
‘Pink Storm’ roots readily from softwood cuttings treated with a basal dip of 5,000 ppm indole butyric acid (potassium salt) in water. ‘Pink Storm’ has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this cultivar have not been applied for. ‘Pink Storm’ has not been made publicly available more than one year prior to the filing date of this application.
SUMMARY OF THE INVENTIONThe following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices at North Carolina State University, Mountain Horticultural Crops Research Station, Mills River, N.C.
-
- 1. A medium-sized, upright, multi-stemmed shrub with occasional parthenocapic fruit formation;
- 2. Large, double-flowers with pink petals; and
- 3. Thornless stems.
This new quince plant is illustrated by the accompanying photographs which show the plant's form, foliage and inflorescences. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken on Apr. 10, 2008 on 2-year-old plants, growing under greenhouse conditions in Mills River, N.C.
The following detailed description sets forth the distinctive characteristics of ‘Pink Storm’. The detailed description was taken on 7-year-old plants growing under landscape conditions in Mills River, N.C. in April 2008. Color references are to The R.H.S.
