Botanical designation: Abelia hybrid.
Cultivar denomination: ‘00-BC-47-13R’.BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of the ornamental flowering shrub Abelia hereinafter referred to by the varietal denomination ‘00-BC-47-13R’.
The new Abelia ‘00-BC-47-13R’ is a product of a planned breeding program conducted by the inventors in Griffin, Ga. The objective of the Abelia breeding is to produce a tough and adaptable drought-tolerant plant with commercial value. The new ‘00-BC-47-13R’ has significant commercial and home gardener appeal with its multicolored foliage, colorful sepals, and heavy blooming. These and other qualities are enumerated herein.
The new ‘00-BC-47-13R’ originated from a cross in 1999 between an Abelia hybrid ‘99-2-8’ (unpatented, female parent) and an Abelia grandiflora ‘Francis Mason’ (unpatented, male parent). The female parent Abelia ‘99-2-8’ originated from a cross in 1998 between an unnamed Abelia chinensis plant of unknown origin (unpatented, female grandparent) and Abelia grandiflora ‘Francis Mason’ (unpatented, male grandparent).
Seedlings from the cross between the female parent Abelia ‘99-2-8’ and the male parent A. grandiflora ‘Francis Mason’ were planted in a field plot in Griffin, Ga. (cold hardiness zone 8a) in the fall of 2003. Plants were evaluated for flowering and foliage characteristics, plant form and height, cold hardiness and drought tolerance. Plant ‘00-BC-47-13R’ was selected and vegetatively propagated by stem cuttings in Griffin, Ga. In the summer of 2014, three replicates of ‘00-BC-47-13R’ were planted into a field plot in Griffin, Ga. In summer of 2015, two replicates of ‘00-BC-47-13R’ were planted into a field plot in Blairsville, Ga. (cold hardiness zone 7a), along with 4 other selections in a randomized complete block design.
The original seedling plant has been evaluated in Griffin for 17 years; the asexually propagated ‘00-BC-47-13R’ plants have been evaluated in Griffin for 6 years and in Blairsville for 5 years. In Griffin, plants were pruned every two years to a height of 40 to 50 cm with height and width data collected prior to pruning. First bloom dates were recorded each year. Winter cold and spring frost damage was assessed each spring in Griffin and Blairsville. Observation for disease or insect damage was continuous throughout the summer. Asexual reproduction of the new Abelia ‘00-BC-47-13R’ by softwood stem cuttings since 2014 has shown that the unique features of this new Abelia are stable and reproduced true to type in successive generations.SUMMARY OF THE INVENTION
The new Abelia cultivar ‘00-BC-47-13R’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, water and fertility levels, soil types, and light intensity without, however, any variance in genotype.
Abelia is a genus of 15-30 species and interspecific hybrids that are popular landscape plants. They range from deciduous to evergreen, depending upon the cultivar and the climate. They have attractive, colorful foliage and flower from late spring to autumn. Abelia is a low-maintenance shrub that is tolerant of any well-drained soil, has heat and drought tolerance and is resistant to most pests. It thrives in full sun or part shade, and can generally be grown in cold hardiness zones 5 through 9. The new plant is expected to be distributed for landscape use in the U.S. and perhaps in other countries.
The following traits have been consistently observed in the original and asexually propagated plants of this new variety in both Blairsville and Griffin, Ga., and to the best knowledge of the inventors, their combination are determined to be the unique and distinguishing characteristics of the new Abelia cultivar named ‘00-BC-47-13R’. In combination, these traits set ‘00-BC-47-13R’ apart from all other existing varieties of Abelia known to the inventors:
- 1. colorful display of multi-colored foliage that changes from early spring through late fall, and the abundant blooms of white flowers with orange or red sepals throughout the summer (see all FIGS.);
- 2. foliage changes from bright golden-yellow-green and green in the spring, to bright green and yellow-green in the summer to yellow-green in the fall (see all FIGS.)
- 3. shorter height than its parents and many other cultivars, though taller than cultivar ‘00-BC-47-7R’ (see Table 1);
- 4. heavy blooming with showy compound panicles (
- 5. flowering beginning in late May and continuing throughout the summer in Griffin, Ga. (Table 2); and
- 6. white flowers with greyed-orange sepals in mid-summer turning to orange-red in late summer (
FIG. 5A, Tables 5, 6).
Comparison: The new variety of Abelia ‘00-BC-47-13R’ can be compared to its male parent ‘Francis Mason’ and maternal grandparent A. chinensis and to ‘00-BC-47-7R’ (U.S. Plant application Ser. No. 17/317,291), a sibling cultivar. The female parent Abelia hybrid ‘99-2-8’ was never propagated or sold, and the plant was discarded in 2001. It is known that ‘99-2-8’ had yellow foliage, a leggy growth habit, and severe photobleaching making the foliage unattractive. The new Abelia ‘00-BC-47-13R’ differs from ‘99-2-8’ at least in that it has a shorter height and does not have photobleaching, but further comparison data is not available.
‘00-BC-47-13R’ plants have been evaluated in field plots in Griffin, Ga. and in Blairsville, Ga. One plant of A. chinensis (maternal grandparent) and ‘Francis Mason’ (paternal parent) have been grown in Griffin since 2001. ‘Francis Mason’ was asexually propagated, and six replicates were planted in Blairsville in 2003 and six replicates were planted in Griffin in 2009. ‘00-BC-47-7R’, a new release from this breeding program, was used as a standard for comparison as it is a sibling to ‘00-BC-47-13R’. One plant of ‘00-BC-47-7R’ was planted in Griffin in 2003, with replicates planted in Griffin in 2008, and in Blairsville in 2011. Height and width data were collected in Griffin every year. Plants were pruned every two years. First bloom dates were recorded each year. Winter cold and spring frost damage was assessed each spring in Griffin and Blairsville. Observation for disease or insect damage was continuous throughout the summer.
Foliage of ‘00-BC-47-13R’ is bright golden-yellow-green and green in early summer, changing to a mix of bright green and yellow-green in the summer and yellow-green in the fall. ‘Francis Mason has golden yellow foliage from spring through fall; A. chinensis has green foliage from spring through fall; and ‘00-BC-47-7R’ has yellow-green to green in June and dark green in the summer and fall (see all FIGS.).
Height of pruned ‘00-BC-47-13R’ is statistically shorter than ‘Francis Mason’ and A. chinensis but taller than ‘00-BC-47-7R’ (Table 1). Width of ‘00-BC-47-13R’ is similar to ‘00-BC-47-7R’ and smaller than ‘Francis Mason’ and A. chinensis (Table 1).
The variety ‘00-BC-47-13R’ usually begins blooming about one week later than ‘00-BC-47-7R’ and two weeks later than ‘Francis Mason’ but about two weeks earlier than A. chinensis (Table 2). The variety ‘00-BC-47-13R’ blooms from late May to September, with heavy blooming in June through August in Griffin (
The flowers of ‘00-BC-47-13R’ occur in compound panicles, mostly terminal though some are axillary. The panicles of ‘00-BC-47-13R’ average about 36 cm in length and 24 cm width, similar in length to ‘00-BC-47-7R’ but less wide. The length and width of ‘Francis Mason’ is significantly greater than that of ‘00-BC-47-13R’, while A. chinensis is both shorter and narrower than ‘00-BC-47-13R’ (Table 3,
Flowers of ‘00-BC-47-13R’, ‘Francis Mason’, A. chinensis, and ‘00-BC-47-7R’ are white (Table 5); sepals of ‘00-BC-47-13R’ are greyed-orange in mid-summer and orange-red in late summer (
Plants of ‘00-BC-47-13R’ in the Griffin field plot had minor or moderate cold/frost damage in 2015, a winter that was very cold, with a low of 9.6° F. in January and a late spring freeze of 26.2° F. in late March. Minor, moderate or severe damage was also observed on plants of ‘Francis Mason in 2015. All five plants of ‘00-BC-47-7R’ had minor damage that year. No damage occurred on A. chinensis. No damage occurred on ‘00-BC-47-13R’ or A. chinensis in 2017, 2018 or 2019. ‘Francis Mason’ had four plants with minor damage in 2017 and ‘00-BC-47-7R’ had one plant with minor damage in 2019 (Table 7). Both plants of ‘00-BC-47-13R’ planted in Blairsville Ga. (Zone 7a) in 2015 have survived and are growing well.
As established, three checks were used for comparison to ‘00-BC-47-13R’: parents ‘Francis Mason’ and A. chinensis, and sibling ‘00-BC-47-7R’. All are distinctly different. Plant ‘00-BC-47-13R’ is shorter in height than its parents and taller than ‘00-BC-47-7R’ (Table 1). The variety ‘00-BC-47-13R’ usually begins blooming about one week later than ‘00-BC-47-7R’ and two weeks later than ‘Francis Mason’ but about two weeks earlier than A. chinensis (Table 2). Panicle length is similar to ‘00-BC-47-7R’, but shorter than ‘Francis Mason’ and longer than A. chinensis. Panicle width is narrower than ‘00-BC-47-7R’ and ‘Francis Mason’ and wider than A. chinensis (Table 3). The number of subpanicles per compound panicle on ‘00-BC-47-13R’ is fewer than that of ‘Francis Mason’ and ‘00-BC-47-7R’ and greater than A. chinensis (Table 3). Subpanicles are longer than A. chinensis and internode length on the subpanicle is intermediate to the checks (Table 4). All have white flowers (
The new Abelia ‘00-BC-47-13R’ is readily propagated through cuttings. Six-inch cuttings taken in May or early June before flowering rooted at a rate of over 70%. After 2 months, cuttings can be transferred to one-gallon containers using a well-drained potting mix. From cutting to saleable plant is about 8 months. No insect or disease problems have been noted in potted plants maintained outside the greenhouse, or in field plants. Once established, the plants are quite drought resistant. After landscape establishment, a hard pruning is recommended in early spring approximately every other year to encourage compact growth and heavy blooming.
The new variety ‘00-BC-47-13R’ has colorful foliage that changes from bright golden-yellow-green and green in the spring, to bright green in the summer to yellow-green in the fall. White flowers and greyed-orange to orange-red sepals are borne on showy compound panicles from late May throughout summer.
