Title: Pericallis Plant Named ‘Ochkeinibu’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Pericallis plant, botanically known as Pericallis cruenta and hereinafter referred to by the name ‘Ochkeibu’.

The new Pericallis plant is a product of a planned breeding program conducted by the Inventor in Gose City, Nara, Japan. The objective of the breeding program is to create new compact Pericallis plants with numerous attractive flowers.

The new Pericallis plant originated from an open-pollination made by the Inventor during the spring of 2008 in Gose City, Nara, Japan of a proprietary selection of Pericallis cruenta identified as code number FC20-3-005, not patented, as the female, or seed, parent with an unknown selection of Pericallis cruenta as the male, or pollen, parent. The new Pericallis 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 Gose City, Nara, Japan during the spring of 2009.

Asexual reproduction of the new Pericallis plant by vegetative terminal cuttings in a controlled greenhouse environment in Gose City, Nara, Japan since the spring of 2009 has shown that the unique features of this new Pericallis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. Compact, upright and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Daisy-type inflorescences with violet blue-colored ray florets that are lighter in color towards the center of the inflorescence.

Plants of the new Pericallis differ from plants of the female parent selection primarily in plant habit as plants of the new Pericallis are more compact than plants of the female parent selection.

Plants of the new Pericallis can be compared to plants of Pericallis cruenta ‘Ochkeinibu’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Pericallis and ‘Ochkeinibu’ differ primarily in ray floret color as plants of ‘Ochkeinibu’ have darker violet blue-colored ray florets.

Plants of the new Pericallis can also be compared to plants of Senecio cruentus×Pericallis heritieri ‘Sunsenebu’, disclosed in U.S. Plant Pat. No. 12,104. In side-by-side comparisons conducted in Gose City, Nara, Japan, plants of the new Pericallis differed from plants of ‘Sunsenebu’ in the following characteristics:

• • 1. Plants of the new Pericallis were more compact than plants of ‘Sunsenebu’.
  • 2. Plants of the new Pericallis were more freely branching, had shorter internodes and were denser than plants of ‘Sunsenebu’.
  • 3. Plants of the new Pericallis had smaller and darker green-colored leaves than plants of ‘Sunsenebu’.
  • 4. Plants of the new Pericallis and ‘Sunsenebu’ differed in ray floret color as plants of ‘Sunsenebu’ had solid violet blue-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typically used in commercial Pericallis production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were 20 weeks old when the photograph and description were taken.
