Description

Botanical designation: Iberis sempervirens.

Cultivar denomination: ‘DOIBEWHISHA’.

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 Jun. 21, 2021, application number 2021/1659. 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 Iberis plant, botanically known as Iberis sempervirens and hereinafter referred to by the name ‘Doibewhisha’.

The new Iberis plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create new freely branching Iberis plants with large flowers and large inflorescences.

The new Iberis plant originated from an open-pollination in April, 2017 in Aalsmeer, The Netherlands of a proprietary selection of Iberis sempervirens identified as code number IB16-000155-002, not patented, as the female, or seed parent with an unknown selection of Iberis sempervirens as the male, or pollen, parent. The new Iberis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Aalsmeer, The Netherlands in April, 2018.

Asexual reproduction of the new Iberis plant by vegetative terminal cuttings in a controlled greenhouse environment in since June, 2018 has shown that the unique features of this new Iberis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Iberis have not been observed under all possible combination 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 ‘Doibewhisha’. These characteristics in combination distinguish ‘Doibewhisha’ as a new and distinct Iberis plant:

- 1. Compact, upright to outwardly spreading and uniformly mounding plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit; dense and bushy habit.
- 4. Relatively late flowering.
- 5. Numerous dense inflorescences with white-colored flowers.
- 6. Good container and garden performance.

Plants of the new Iberis differ primarily from plants of the female parent selection in flower size as plants of the new Iberis have larger flowers than plants of the female parent selection.

Plants of the new Iberis can be compared to plants of Iberis sempervirens ‘Snow Cone’, not patented. In side-by-side comparisons, plants of the new Iberis differ from plants of ‘Snow Cone’ in the following characteristics:

- 1. Plants of the new Iberis flower later than plants of ‘Snow Cone’.
- 2. Plants of the new Iberis have larger flowers than plants of ‘Snow Cone’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Iberis 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 Iberis plant.

The photograph is a side perspective view of a typical flowering plant of ‘Doibewhisha’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring in 17-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Iberis production. During the production of the plants, average daily temperatures were 21° C. and average night temperatures were 15° C. Plants were pinched two weeks after planting and were 44 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used.
