The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hebe plant, botanically known as Hebe Comm. ex. Juss, typically grown as a potted plant and hereinafter referred to by the name ‘HOP102’.

The new Hebe plant is a product of a planned breeding program conducted by the Inventor in Wieringerwerf, The Netherlands. The objective of the breeding program is to create new compact Hebe plants with dark-colored leaves and numerous attractive flowers.

The new Hebe plant originated from a cross-pollination in April, 2015 of a proprietary selection of Hebe Comm. ex. Juss. identified as code number 279A, not patented, as the female, or seed, parent with a proprietary selection of Hebe Comm. ex. Juss. identified as code number 318B, not patented, as the male, or pollen, parent. The new Hebe plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Wieringerwerf, The Netherlands in October, 2015.

Asexual reproduction of the new Hebe plant by terminal stein cuttings in a controlled greenhouse environment in Wieringerwerf, The Netherlands, since February, 2016 has shown that the unique features of this new Hebe plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Hebe have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘HOP102’. These characteristics in combination distinguish ‘HOP102’ as a new and distinct Hebe plant:

• • 1. Compact and upright to outwardly spreading and uniformly mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit with numerous purplish red-colored flowers that resist fading.
  • 6. Resistance to Stemphylium Leaf Spot.

Plants of the new Hebe differ primarily from plants of the female parent selection in flower color as plants of the new Hebe have purplish red-colored flowers whereas plants of the female parent selection have blue-colored flowers. In addition, plants of the new Hebe have smaller leaves than plants of the female parent selection.

Plants of the new Hebe differ primarily from plants of the male parent selection in flower color as plants of the new Hebe have purplish red-colored flowers whereas plants of the male parent selection have bluish purple-colored flowers. In addition, plants of the new Hebe are more compact than and not as upright as plants of the male parent selection.

Plants of the new Hebe can be compared to plants of Hebe Comm. ex. Juss. ‘Zita’, not patented. In side-by-side comparisons, plants of the new Hebe differ primarily from plants of ‘Zita’ in inflorescence length as plants of the new Hebe have shorter inflorescences than plants of ‘Zita’. In addition, plants of the new Hebe are more compact than and not as upright as plants of ‘Zita’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown with two plants per 15-cm containers during the autumn initially in a glass-covered greenhouse and finished in a outdoor nursery in Wieringerwerf, The Netherlands and under cultural practices typical of commercial Hebe production. During the production of the plants, day temperatures ranged from 16° C. to 20° C. and night temperatures ranged from 12° C. to 16° C. Plants were pinched one time about one month after planting and were six months old when the photographs and the description were taken.
