Botanical classification: Hydrangea paniculata.

Varietal denomination: ‘Bee Green’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2021/2497 filed on Oct. 5, 2021 under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea paniculata and will be referred to hereafter by its cultivar name, ‘Bee Green’. ‘Bee Green’ represents a new panicle Hydrangea, a perennial shrub grown for landscape use and as a potted plant.

‘Bee Green’ was discovered as a chance seedling in a production plot by the Inventors in Reeuwijk, The Netherlands in August of 2019. The parent plants are unknown.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by one of the Inventors in October of 2019 in Reeuwijk, The Netherlands. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Bee Green’ as a unique cultivar of Hydrangea paniculata.

• • 1. ‘Bee Green’ exhibits inflorescences with sterile flower sepals that are light green in color that change to dark pink-red in color in autumn.
  • 2. ‘Bee Green’ exhibits a sturdy branches that do not lodge.
  • 3. ‘Bee Green’ exhibits dense panicles with firm sterile flowers.
  • 4. ‘Bee Green’ exhibits healthy foliage that has been observed to be disease and pest free.

‘Bee Green’ can be most closely compared to the Hydrangea paniculata cultivars ‘B2’ (U.S. Plant Pat. No. 32,316) and ‘Silver Dollar’ (not patented). ‘B2’ differs from ‘Bee Green’ in having sterile flower sepals that are more white in color and leaves that are broader. ‘Silver Dollar’ differs from ‘Bee Green’ in having a larger inflorescences and sterile flower sepals that are more green in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Hydrangea. The photographs were taken of a three-year-old plant of ‘Bee Green’ as field grown in Reeuwijk, The Netherlands and placed in a container for the photographs.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Bee Green’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Bee Green’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘Bee Green’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Hydrangea.
