Description

Botanical designation: Abelia hybrid.

Cultivar denomination ‘99-6-7’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the ornamental flowering shrub botanically known as Abelia and hereinafter referred to by the varietal denomination ‘99-6-7’.

The new Abelia ‘99-6-7’ is a product of a planned breeding program conducted by the Inventors in Griffin, Ga. The objective of the Abelia breeding program is to produce a tough and adaptable drought-tolerant plant with commercial value. This cultivar has significant commercial and home gardener appeal with its attractive foliage, large flower panicles, heavy blooming, pink sepals, and low maintenance requirements. These and other qualities are enumerated herein.

The new Abelia ‘99-6-7’ originated from a cross in 1998 between the cultivar Abelia ‘Edward Goucher’ (unpatented female parent) and Abelia chinensis (unpatented, male parent). (‘Edward Goucher’ is a hybrid of A. x grandiflora and A. parvifolia [syn. A. schumannii] that was introduced in 1911 by Edward Goucher, USDA.) Seeds from this interspecific cross were sown in 1999. These seedlings were planted in a field plot in Griffin, Ga. (cold hardiness zone 8a) in the fall of 1999, where they were evaluated for flowering and foliage characteristics, plant form and height, cold hardiness and drought tolerance. Plant ‘99-6-7’ was selected and vegetatively propagated by stem cuttings in 2001. In the summer of 2002, ‘99-6-7’, was planted with 14 other selections into a field plot in Griffin, Ga. in a completely randomized design with ten replications per selection. In summer of 2003, ‘99-6-7’ was planted into a field plot in Blairsville, Ga. (cold hardiness zone 7a), along with 10 other selections and the check cultivar Abelia ‘Rose Creek’ (unpatented hybrid from open pollination of Abelia chinensis (female parent) with unknown male parent). This plot had six replicates per selection in a randomized complete block design.

Asexual reproduction of the new Abelia ‘99-6-7’ using stem cuttings has been continued in Griffin, Ga. since 2001. Clonally propagated plants have been evaluated in Griffin for over 18 years, and in Blairsville over 16 years. In Griffin, height and widths were measured for the first time in March 2004; following measurements, half of the plants were pruned every two years to a height of 40 to 50 cm and half were left unpruned. Height and width data were collected in Griffin every two years prior to pruning. First bloom dates were recorded each year. Winter cold and spring frost damage was assessed each spring in Griffin and Blairsville. Date of first bloom was recorded each year. Observation for disease or insect damage was continuous throughout the summer.

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 Abelia ‘99-6-7’ plant is expected to be distributed for landscape use in the U.S. and perhaps in other countries.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of a new variety, Abelia ‘99-6-7’. The new variety ‘99-6-7’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in, for example, temperature, light intensity, soil types, and water and fertility levels without, however, any variance in genotype.

Asexual reproduction of the new Abelia ‘99-6-7’ by softwood stem cuttings since 2000 has shown that the unique features of this new Abelia are stable and reproduced true to type in successive generations.

‘99-6-7’ plants, along with other Abelia cultivars ‘Raspberry Profusion’, ‘Lavender Mist’, ‘Rose Creek’ and ‘Edward Goucher’ (maternal parent of ‘99-6-7’) have been evaluated since 2002 in field plots at Griffin, Ga. and since 2003 in Blairsville, Ga. ‘Raspberry Profusion’ and ‘Lavender Mist’ are full siblings. ‘Rose Creek’ was used as a standard for comparison as it is a popular cultivar that has A. chinensis as a maternal parent. Height and width data were collected in Griffin every year. Half of the plants were pruned every two years, while the other plants were not pruned to provide information on mature size. 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.

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, 2001 (5th edition) published by The Royal Horticultural Society, London, England.

The following traits have been consistently observed in the original plant of this new variety and in asexually propagated plants grown from stem cuttings in Blairsville, and Griffin, Ga., and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety ‘99-6-7’ and set it apart from all other existing varieties of Abelia known to the inventors.

    • 1. The most distinctive quality of ‘99-6-7’ is the heavy and continuous display of pink/purple flowers and sepals from May through September.
    • 2. The variety ‘99-6-7’ begins blooming at least a week earlier than most cultivars of Abelia (Table 3).
    • 3. The flowers occur in large compound panicles, mostly terminal though some are axillary (FIGS. 1 and 2; Table 4).
    • 4. Sepals and flowers of ‘99-6-7’ are long and narrow (FIGS. 3 and 4; Table 7).

The following traits have been consistently observed in the original plant of this new variety and in asexually propagated plants grown from stem cuttings in Blairsville, and Griffin, Ga., and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety ‘99-6-7’ and set it apart from all other existing varieties of Abelia known to the inventors.

    • 1. Height and width of ‘99-6-7’ is statistically similar to ‘Raspberry Profusion’ and ‘Lavender Mist’, but ‘Rose Creek’ is shorter (Tables 1-2).
    • 2. The variety ‘99-6-7’ begins blooming earlier than most cultivars of Abelia, and, on average, about a week earlier than ‘Raspberry Profusion’, ‘Lavender Mist’ and ‘Edward Goucher’, and five to six weeks earlier than ‘Rose Creek’ (Table 3).
    • 3. The variety ‘99-6-7’ blooms from May to September, with heavy blooming in May, June, and August in Griffin (FIG. 1).
    • 4. The flowers occur in compound panicles, mostly terminal though some are axillary. The panicles average about 31 cm in length and 11 cm in width. The lengths of ‘Lavender Mist’ and ‘Edward Goucher’ are similar to ‘99-6-7’; ‘Raspberry Profusion’ is intermediate in length and ‘Rose Creek’ is the shortest at 6 cm. Panicle width of ‘99-6-7’ is similar to ‘Raspberry Profusion’ and ‘Lavender Mist’; ‘Rose Creek’ and ‘Edward Goucher’ are narrower (FIG. 2; Table 4).
    • 5. The number of subpanicles per compound panicle averages about 26 on ‘99-6-7’. ‘Lavender Mist’ and ‘Edward Goucher’ are similar; ‘Raspberry Profusion’ and ‘Rose Creek’ have fewer subpanicles (Table 4).
    • 6. Flowers of ‘99-6-7’ and ‘Raspberry Profusion’ are shades of red-purple or purple; ‘Rose Creek’ flowers are white. Sepals of ‘99-6-7’, ‘Raspberry Profusion’ and ‘Rose Creek’ are red-purple throughout summer; sepals of ‘99-6-7’ turn greyed-orange in the fall while ‘Raspberry Profusion’ and ‘Rose Creek’ turn greyed-red (FIGS. 2, 3 and 4; Tables 5 and 6).
    • 7. Flowers of ‘99-6-7’ are narrower than ‘Raspberry Profusion’ but wider than ‘Rose Creek’. Sepals of ‘99-6-7’ are longer and narrower than those on ‘Raspberry Profusion’ and ‘Rose Creek’ (Table 7, FIGS. 3 and 4).
    • 8. Field evaluations in Griffin since 2002 have shown very little or no cold damage on ‘99-6-7’. Plants of ‘99-6-7’ have been evaluated in Blairsville, Ga. in 2004, 2008 and 2011. Minor damage was observed on 2 out of 6 plants in 2004, 3 out of 6 plants in 2008 and 1 out of 4 plants in 2011. ‘Edward Goucher’ had severe damage on most plants in 2008. Other checks had no damage or minor damage (Table 8).

 DETAILED BOTANICAL DESCRIPTION

The following traits have been consistently observed in the original plant of this new variety and in asexually propagated progeny grown from stem cuttings in Blairsville, and Griffin, Ga., and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety ‘99-6-7’.

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, 5th edition published by The Royal Horticultural Society, London, England in 2007.

The following observations, measurements, and values describe plants grown in Griffin, Ga. Plant ‘99-6-7’ was propagated from softwood stem cuttings and grown in one-gallon containers prior to planting in field plots. Data are from plants planted and grown in the field since 2002.

The new variety ‘99-6-7’ has a spreading, upright growth habit. Red-purple flowers and sepals are borne on large compound panicles. Blooming is very heavy from May to September

(FIG. 1). The blossoms are highly fragrant. Blooming is heavy even on young plants in containers or in the field.

Four checks were used for comparison to ‘99-6-7’: ‘Raspberry Profusion’, ‘Lavender Mist’, ‘Rose Creek’ and ‘Edward Goucher’. The panicles of ‘99-6-7’ are significantly longer than those of ‘Raspberry Profusion’ and ‘Rose Creek’, and the number of subpanicles per panicle is greater than ‘Raspberry Profusion’ and ‘Rose Creek’ (Table 4, FIG. 2). Both upper and lower surfaces of the flower petals are purple on ‘99-6-7’, while ‘Rose Creek’ has white flowers (Table 5, FIGS. 2 and 3). Sepal color of ‘99-6-7’ is red-purple in the summer, but turns to greyed-orange in the fall. In contrast, the red-purple sepals of both ‘Raspberry Profusion’ and ‘Rose Creek’ turn greyed-red in the fall (Table 6, FIG. 4). The new variety ‘99-6-7’ blooms a week earlier than all of the check cultivars, except ‘Rose Creek’, which blooms a month later (Table 3).

After 16 years growth in a field plot in Griffin, ‘99-6-7’ plants that had not been pruned were an average of 2.8 m tall and 3.6 m wide. Plants that were pruned every two years were 1.5 m tall and 2.3 m wide (Tables 1 and 2). Statistically, ‘Rose Creek’ was shorter than both pruned and unpruned plants of ‘99-6-7’, and width was also less on pruned plants. The other cultivars were mostly similar in height and width to ‘99-6-7’.

‘99-6-7’ 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 following observations, measurements, and values describe plants of the new Abelia ‘99-6-7’ grown in Griffin, Ga. propagated from softwood stem cuttings and grown in one-gallon containers prior to planting in field plots. Data are from plants planted and grown in the field since 2002. Data from Table 8 is taken from plants grown in Blairsville, Ga.
