Botanical/commercial classification:
Latin name of genus and species of plant claimed: Vaccinium (angustifolium x myrsinites) x corymbosum hybrid.
Variety denomination: ‘FC12-187’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Vaccinium plant botanically known as Vaccinium (angustifolium x myrsinites) x corymbosum hybrid and hereinafter referred to by the cultivar name ‘FC12-187’.
The new cultivar was created in a controlled breeding program in Lowell, Oreg. during May 2010. The objective of the breeding program was the development of superior Vaccinium cultivars that meet the evolving needs of the blueberry and home enthusiast industries.
The new Vaccinium cultivar is the result of cross-pollination. The female parent (i.e., seed parent) of the new cultivar is ‘NC-4339’, a non-introduced, non-patented breeder seedling. The male parent (i.e., pollen parent) of the new cultivar is ‘ZF09-233’, a non-introduced, non-patented breeder seedling.
The parentage can be summarized as follows:
‘NC-4339’ x ‘ZF09-233’
The new cultivar was obtained and selected as a single flowering plant within the progeny of the above stated cross-pollination during July 2012 in a controlled environment in Lowell, Oreg.
Asexual reproduction of the new cultivar by softwood stem cuttings since 2012 in Lowell, Oreg. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.
SUMMARY OF THE INVENTION
The new cultivar of the present invention possesses the following combination of characteristics, which have been repeatedly observed and can be used to distinguish ‘FC12-187’ as a new and distinct cultivar of Vaccinium plant:
- (a) forms white colored inflorescences,
- (b) exhibits medium green foliage,
- (c) forms moderately vigorous, mounded to weeping growth habit, and
- (d) produces a good crop load of small dark colored fruit.
The new variety can be readily distinguished from its ancestors. More specifically, ‘NC-4339’ (i.e., seed parent) exhibits a less prostrate growth habit and more red bark color. Additionally, ‘ZF09-233’ (i.e., pollen parent) exhibits a less dense canopy and less uniform growth. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. Of the many commercially available Vaccinium cultivars, the most similar in comparison to the new cultivar is ‘ZF08-095’ (U.S. Plant Pat. No. 25,467). However, plants of the new cultivar differ from plants of ‘ZF08-095’ in at least the following characteristics:
- 1. Plants of the new cultivar have a wide and low growth habit, whereas plants of ‘ZF08-095’ have a round growth habit;
- 2. Plants of the new cultivar have leaves that are lighter green and less glossy than plants of ‘ZF08-095’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical specimen of the new variety. The illustrated Vaccinium plant of the new variety in FIG. 1 was approximately two years of age and was grown in Cochranville, Pa. in April 2019. The illustrated Vaccinium plant of the new variety in FIG. 2 was approximately two years of age and was grown outdoors in a hanging basket in Lowell, Oreg. in July 2017.

DETAILED BOTANICAL DESCRIPTION
The chart used in the identification of colors described herein is that of The Royal Horticultural Society (R.H.S. Colour Chart, London, England, 2015 edition), except where general color terms of ordinary significance are used. 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 under natural light conditions in Cochranville, Pa. Measurements and numerical values represent averages of typical plants.
