Abstract

A new and distinct cultivar of Abelia plant named ‘PIIAB-II’, characterized by its compact, mounding to spreading growth habit, bronze new growth that turns to yellow-green and finally matures to green, semi-evergreen foliage that does not photobleach or burn in full sun like some other yellow foliage cultivars, early and abundant flowering during the growing season, light pink flower buds that open to white flowers with persistent pink sepals.

Description

Genus and species of plant claimed: Abelia×grandiflora.
Variety denomination: ‘PIIAB-II’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Abelia plant, botanically known as Abelia×grandiflora, commonly known as Abelia, and hereinafter referred to by the cultivar name ‘PIIAB-II’. ‘PIIAB-II’ is grown primarily as an ornamental for landscape use and for use as a potted plant.
‘PIIAB-II’ originated in 2008 from open-pollinated seed of Abelia ‘PIIAB-I’ (unpatented) as part of a breeding program in Watkinsville, Ga. The cultivar ‘PIIAB-II’ originated and was selected by the inventor in a cultivated environment in Watkinsville, Ga. from the progeny of this open-pollination by continued evaluation for growth habit and foliage and flower characteristics.
Asexual reproduction of ‘PIIAB-II’ by stem cuttings in Watkinsville, Ga. since 2009 has shown that all the unique features of this new Abelia, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.
SUMMARY OF THE INVENTION
Plants of the new cultivar ‘PIIAB-II’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PIIAB-II’. These characteristics in combination distinguish ‘PIIAB-II’ as a new and distinct cultivar: 1. Compact, mounding to spreading growth habit; 2. Bronze new growth that turns to yellow-green and finally matures to green; 3. Semi-evergreen foliage that does not photobleach or burn in full sun like some other yellow foliage cultivars; 4. Early and abundant flowering during the growing season; 5. Light pink flower buds that open to white flowers with persistent pink sepals.
Plants of ‘PIIAB-II’ differ from plants of the parent, ‘PIIAB-I’, primarily in growth habit and sepal color. Plants of ‘PIIAB-II’ have a compact, mounding to spreading growth habit and pink sepals, whereas plants of ‘PIIAB-I’ have a larger, upright to rounded growth habit and burgundy-rose sepals.
Plants of ‘PIIAB-II’ can be compared to plants of ‘Canyon Creek’ (unpatented) but differ in growth habit, foliage color, and flower color. Plants of ‘PIIAB-II’ have a compact, mounding to spreading growth habit, foliage that does not photobleach or burn, and white flowers, whereas plants of ‘Canyon Creek’ have a larger, rounded to upright growth habit, foliage that is susceptible to photobleaching or burning, and pink flowers.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color photographs illustrate the flower and foliage characteristics and the overall appearance of ‘PIIAB-II’, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Abelia.
