Abstract
A new cultivar of Rhaphiolepis indica plant named, ‘PS-2013-2’, that is characterized by its spreading plant habit that is wider than it is tall, its dense self-branching plant habit with short internode lengths, its leather-like leaves that are deep emerald green in color, its flowers that are soft pink in color, its resistance to foliar pathogens, and its foliage and flower buds that are cold hardy at least to U.S.D.A. Zone 7.
Description
Botanical classification: Rhaphiolepis indica.
Variety denomination: ‘PS-2013-2’.
The present invention relates to a new and distinct cultivar of Rhaphiolepis indica and will be referred to hereafter by its cultivar name, ‘PS-2013-2’. ‘PS-2013-2’ is an evergreen shrub grown for use as a landscape plant and container plantings.
The new cultivar was derived from a controlled breeding program conducted by the Inventor in Grand Saline, Tex. The overall purpose of the breeding program is to develop new cultivars of Rhaphiolepis plants with compact growth habits, uniform flowering habits, and glossy, green, disease resistant foliage.
‘PS-2013-2’ originated from the open pollination of Rhaphiolepis indica ‘Conor’ (U.S. Plant Pat. No. 9,398) in April of 2011. The male parentage is therefore unknown. The collected seeds were treated with the chemical colchicine prior to planting and polyploidy is suspected based on its characteristics but not verified. ‘PS-2013-2’ was selected as a single unique plant in April of 2013 from amongst the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished by the Inventor by semi-hardwood stern cuttings in June of 2013 in Grand Saline, Tex. Asexual propagation by semi-hardwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘PS-2013-2’ as a unique cultivar of Rhaphiolepis.
-
- 1. ‘PS-2013-2’ exhibits a spreading plant habit that is wider than it is tall.
- 2. ‘PS-2013-2’ exhibits a dense self-branching plant habit with short internode lengths.
- 3. ‘PS-2013-2’ exhibits leather-like leaves that are deep emerald green in color.
- 4. ‘PS-2013-2’ exhibits flowers that are soft pink in color.
- 5. ‘PS 2013-2’ exhibits resistance to foliar pathogens.
- 6. ‘PS-2013-2’ exhibits foliage and flower buds that are cold hardy at least to U.S.D.A. Zone 7.
The female parent of ‘PS-2013-2’, ‘Conor’, differs from ‘PS-2013-2’ in having a plant habit that is equal in height and width, in being less well-branched, in having foliage that is olive green in color, and in having flowers that are darker pink in color. ‘PS-2013-2’ can be most closely compared to the Rhaphiolepis indica cultivars ‘Hines Darkleaf’ (U.S. Plant Pat. No. 8,635) and ‘Sopink’ (U.S. Plant Pat. No. 14,388). ‘Hines Darkleaf’ is similar to ‘PS-2013-2’ in having foliage that is deep green in color and in having leaves with a leathery texture. ‘Hines Darkleaf’ differs from ‘PS-2013-2’ in being less densely branched (not self-branched), in having flowers that are darker pink in color, and in being susceptible to foliar pathogens. ‘Sopink’ is similar to ‘PS-2013-2’ in being resistant to foliar pathogens and in having flowers that are soft pink in color. ‘Sopink’ differs from ‘PS-2013-2’ in having a mounded plant habit, in having foliage that is dull olive green in color, and in having flowers with petals that are oblanceolate in shape.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Rhaphiolepis. The plants in the photographs were taken of a plant 2.5 years in age as grown in a two-gallon container outdoors in Grand Saline, Tex.
The photograph in FIG. 1 provides a top view of ‘PS-2013-2’ in bloom.
The photograph in FIG. 2 provides a close-up view of the flowers of ‘PS-2013-2’.
The colors in the photographs are as close as possible with the digital photography techniques available and the color values cited in the detailed botanical description accurately describe the colors of the new Rhaphiolepis.
The following is a detailed description of 2.5 year-old plants of the new cultivar as grown outdoors in 2-gallon containers in Grande Saline, Tex. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
