Cultivar designation: ‘Celebration’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to a European plant breeders' rights application filed on Sep. 16, 2014, application No. 2014/2236. There have been no offers for sale anywhere in the world prior to the filing of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hebe of hybrid origin and known as Hebe ‘Celebration’ and will be referred to hereafter by its cultivar name, ‘Celebration’. ‘Celebration’ is grown for use as a container plant and landscape shrub.

The new cultivar was discovered by one of the Inventors in August of 2009 as a naturally occurring branch mutation of Hebe ‘Wiri Charm’ (not patented) in a production container block at the Inventors' nursery in Spalding, United Kingdom.

Asexual propagation of the new cultivar was first accomplished by one of the Inventors by softwood stem cuttings in Spalding, United Kingdom in March of 2010. Asexual propagation by softwood 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, which in combination distinguish ‘Celebration’ as a new and distinct cultivar of Hebe.

• • 1. ‘Celebration’ exhibits a compact, well-branched, rounded plant habit.
  • 2. ‘Celebration’ exhibits variegated foliage that is yellow-green in color with green at the center and very thin margins that are red-purple in color.
  • 3. ‘Celebration’ exhibits leaves that are narrowly elliptical to obelliptical in shape.
  • 4. ‘Celebration’ exhibits flowers that transition from dark to light red-purple in color as they mature.
  • 5. ‘Celebration’ exhibits a bloom season that commences in mid-May.

The parent plant of ‘Celebration’, ‘Wiri Charm’, differs from ‘Celebration’ in having foliage that is solid green in color, in having leaves that are spear-shaped, in having inflorescences that are larger in size, in having flowers that are pink-purple in color, and in having a later starting bloom period. ‘Celebration’ can be compared to the Hebe cultivars ‘Inspiration’ and ‘Rose Elegance’ (both un-patented). ‘Inspiration’ differs from ‘Celebration’ in having glossy foliage that is solid green in color, in having flowers that are lavender in color, and in having a later starting bloom period. ‘Rose Elegance’ differs from ‘Celebration’ in having glossy foliage that is solid green in color, in having flowers that are pink in color, and, in having inflorescences that are larger in size, and in having a later starting bloom period.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hebe. The photographs were taken of a plant approximately six months in age as grown in a 12-liter container in a glass greenhouse Hampshire, The United Kingdom.

The photograph in FIG. 1 is a side view of a plant of ‘Celebration’.

The photograph in FIG. 2 provides a close-up view of inflorescences of ‘Celebration’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Celebration’.

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 Hebe.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of six month-old plants of the new cultivar as grown in three-liter containers in an un-heated greenhouse Hampshire, The United Kingdom.
