STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Inventor/Applicant on May 4, 2021, application number 2021/1216. Foreign priority is not claimed to this application.

The Inventor/Applicant 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/Applicant. Inventor/Applicant 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 Achillea plant, botanically known as Achillea millefolium, commonly referred to as Yarrow, and hereinafter referred to by the name ‘Bosachskybripi’.

The new Achillea plant is a product of a planned breeding program conducted by the Inventor in Nieuw-Vennep and Zwaanshoek, The Netherlands. The objective of the breeding program is to create new vigorous Achillea plants with uniform plant habit and large inflorescences with attractive flowers.

The new Achillea plant originated from a cross-pollination in Nieuw-Vennep, The Netherlands in July, 2015 of Achillea millefolium ‘Surprising Charm’, not patented, as the female, or seed, parent with Achillea millefolium ‘Desred’, disclosed in U.S. Plant Pat. No. 22,333, as the male, or pollen, parent. The new Achillea 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 Zwaanshoek, The Netherlands in July, 2016

Asexual reproduction of the new Achillea plant by vegetative tip cuttings in a controlled environment in Zwaanshoek, The Netherlands since July, 2016, has shown that the unique features of this new Achillea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Achillea 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 ‘Bosachskybripi’. These characteristics in combination distinguish ‘Bosachskybripi’ as a new and distinct Achillea plant:

• • 1. Upright and uniform plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Inflorescences with purplish pink-colored ray florets.
  • 6. Good garden performance.

Plants of the new Achillea differ from plants of the female parent, ‘Surprising Charm’, in ray floret color as plants of the new Achillea have purplish pink-colored ray florets whereas plants of ‘Surprising Charm’ have purple-colored ray florets.

Plants of the new Achillea differ from plants of the male parent, ‘Desred’, in ray floret color as plants of the new Achillea have purplish pink-colored ray florets whereas plants of ‘Desred’ have red-colored red florets.

Plants of the new Achillea can also be compared to plants of Achillea millefolium ‘Desert Eve Cream’, not patented. In side-by-side comparisons, plants of the new Achillea differ primarily from plants of ‘Desert Eve Cream’ in ray floret color as plants of the new Achillea have purplish pink-colored ray florets whereas plants of ‘Desert Eve Cream’ have cream-colored-colored ray florets. In addition, plants of the new Achillea are larger than and not as compact as plants of ‘Desert Eve Cream’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Achillea plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Achillea plant. The photograph is a top perspective view of a typical flowering plant of ‘Bosachskybripi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the late summer in 17-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Achillea production. During the production of the plants, average daily temperatures were 22° C. and average night temperatures were 17° C. Plants were 25 weeks old when the photograph and description were taken.
