Botanical/commercial classification:
Latin name: Abelia hybrid.
Varietal denomination: ‘Abesrpras’.
SUMMARY OF THE INVENTION
The new variety of Abelia hybrid plant originated in a controlled breeding program in Cochranville, Pa. during July, 2013. The objective of the breeding program was the development of Abelia cultivars with compact habits and a range of foliage colors. The new cultivar was created by open-pollination. The female parent (i.e., the seed parent) was an unnamed breeder seedling (non-patented). The male parent (i.e., the pollen parent) was unknown.
The parentage of the new variety can be summarized as follows:
unnamed breeder seedling x unknown
The new cultivar was discovered and selected as a single flowering plant from the progeny resulting from the above pollination during August, 2016 in a controlled environment in Cochranville, Pa. Selective study resulted in the identification of a single plant of the new variety.
It was found that the new variety of Abelia plant of the present invention:
- (a) forms light-pink colored flowers with dark pink colored sepals,
- (b) displays medium green colored foliage, and
- (c) exhibits a moderately vigorous, compact and mounded growth habit.
The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.
The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the unnamed breeder seedling female parent variety (i.e., the seed parent) forms dark green colored foliage and provides an upright to rounded growth habit, whereas the new variety forms medium green colored foliage and provides compact and mounded growth habit. Moreover, the new variety can also be distinguished from other similar varieties that are commercially available. For instance, the new variety of the present invention can readily be distinguished from the ‘Raspberry Profusion’ variety (U.S. Plant Pat. No. 18,834), as the new cultivar displays a more compact and more rounded growth habit than the ‘Raspberry Profusion’ variety and the new cultivar plants are better branched, which require less trims compared to plants of the ‘Raspberry Profusion’.
The new variety has been found to undergo asexual reproduction by a number of routes, including terminal stem cuttings. Asexual propagation by terminal stem cuttings in Cochranville, Pa. since September 2016 has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.
The new variety has been named ‘Abesrpras’.
The new variety was first offered for sale in the “SHRUBS VINES TREES EVERGREENS EDIBLES” 2021 Star® Roses and Plants Catalog, which was published on Feb. 23, 2020 by a joint inventor or by another who obtained the new variety directly or indirectly from a joint inventor.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant and plant parts of the new variety. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘Abesrpras’ variety. The plants were grown in one-gallon pots for approximately five months outside at Cochranville, Pa. Plants were pinched once after transplant.

DETAILED BOTANICAL DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), 2015 edition, London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The color values were determined in September 2020 under natural light conditions in Cochranville, Pa. The description is based on the observation of plants produced from cuttings from stock plants and grown in one-gallon containers for approximately five months in an outdoor nursery in Cochranville, Pa. Plants were pinched once after transplant.
