CROSS-REFERENCE TO A RELATED APPLICATION AND STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

This application claims priority to a Canadian Plant Breeders' Rights application filed on May 17, 2019, application number 19-9898. There have been no offers for sale anywhere in the world prior to the effective filing date 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.

The Inventor/Applicant asserts 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 claims a prior art exemption 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 Euryops plant, botanically known as Euryops pectinatus and hereinafter referred to by the name ‘EUR16001’.

The new Euryops plant is a product of a planned breeding program conducted by the Inventor in Bozen, Italy. The objective of the breeding program is to create compact and bushy Euryops plants with numerous large attractive flowers and good summer garden performance.

The new Euryops plant originated from a cross-pollination made by the Inventor in August, 2015 of an unnamed selection of Euryops pectinatus, not patented, as the female, or seed, parent with Euryops pectinatus ‘Sonnenschein’, not patented, as the male, or pollen, parent. The new Euryops plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Bozen, Italy in May, 2016.

Asexual reproduction of the Euryops plant by vegetative tip cuttings in Bozen, Italy since September, 2016 has shown that the unique features of this new Euryops plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Euryops 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 ‘EUR16001’. These characteristics in combination distinguish ‘EUR16001’ as a new and distinct Euryops plant:

• • 1. Compact, mounding and outwardly spreading plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit; dense and bushy appearance.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Large bright yellow-colored ray florets and darker yellow-colored disc florets.
  • 7. Good garden performance and drought resistance.

Plants of the new Euryops differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Euryops are more compact than and not as vigorous as plants of the female parent selection.
  • 2. Plants of the new Euryops flower earlier than plants of the female parent selection.

Plants of the new Euryops differ primarily from plants of the male parent, ‘Sonnenschein’, in the following characteristics:

• • 1. Plants of the new Euryops are more compact than and not as vigorous as plants of ‘Sonnenschein’.
  • 2. Plants of the new Euryops flower earlier than plants of ‘Sonnenschein’.
  • 3. Plants of the new Euryops have larger inflorescences than plants of ‘Sonnenschein’.

Plants of the new Euryops can be compared to plants of Euryops anthanasiae ‘Straesun’, disclosed in U.S. Plant Pat. No. 18,373. In side-by-side comparisons, plants of the new Euryops differ primarily from plants of ‘Straesun’ in the following characteristics:

• • 1. Plants of the new Euryops are more mounding than and not as upright as plants of ‘Straesun’.
  • 2. Plants of the new Euryops have larger inflorescences than plants of ‘Straesun’.
  • 3. Plants of the new Euryops have better summer garden performance than plants of ‘Straesun’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Euryops plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Euryops plant.

At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘EUR16001’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘EUR16001’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Euryops production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched when planted and were seven weeks from planting rooted cuttings when the photographs and description were taken.
