Description

Botanical designation: Aster hybrida.

Cultivar denomination: ‘Yomarie the Third’.

CROSS-REFERENCE TO RELATED APPLICATIONS

Aster Plant Named ‘Yopeter the Third’; Mark A. Smith, Applicant; United States Plant Patent application No. 11/705,877.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Aster plant, botanically known as Aster hybrida and hereinafter referred to by the name ‘Yomarie the Third’.

The objective of the breeding program is to create new potted Aster cultivars with uniform and rounded plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable and unique floret colors, and good garden performance.

The new Aster originated from an open-pollination in August, 2003, in Salinas, Calif. of the Aster hybrida cultivar Pixie Dark, not patented, as the female, or seed, parent with an unknown Aster hybrida seedling selection, as the male, or pollen, parent. The new Aster was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment Alva, Fla. in October, 2004. The selection of this plant was based on its uniform plant growth habit, vigor and desirable ray floret color.

Asexual reproduction of the new Aster by vegetative tip cuttings was first conducted in Alva, Fla. in December, 2004. Asexual reproduction by cuttings has shown that the unique features of this new Aster are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Yomarie the Third have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Yomarie the Third’. These characteristics in combination distinguish ‘Yomarie the Third’ as a new and distinct potted Aster cultivar:

• • 1. Uniform, upright and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Dark green-colored foliage.
  • 4. Uniform and freely flowering habit.
  • 5. Natural flowering season mid-September in the northern hemisphere.
  • 6. Decorative-type inflorescences with purple-colored ray florets.
  • 7. Good garden performance.

Plants of the new Aster differ from plants of the female parent, the cultivar Pixie Dark, in the following characteristics:

• • 1. Plants of the new Aster flower about ten days later than plants of the cultivar Pixie Dark when grown under natural season conditions.
  • 2. Plants of the new Aster and the cultivar Pixie Dark differ in inflorescence form as plants of the cultivar Pixie Dark have daisy-type inflorescences.
  • 3. Plants of the new Aster flower more uniformly than plants of the cultivar Pixie Dark.
  • 4. Plants of the new Aster have larger inflorescences than plants of the cultivar Pixie Dark.
  • 5. Plants of the new Aster and the cultivar Pixie Dark differ in ray floret color.

Plants of the new Aster differ primarily from plants of the cultivar Yopeter the Third in ray floret coloration.

Plants of the new Aster can be compared to plants of the Aster cultivar Karmijn, disclosed in U.S. Plant Pat. No. 10,624. In side-by-side comparisons conducted in Alva, Fla., plants of the new Aster differed from plants of the cultivar Karmijn in the following characteristics:

• • 1. Plants of the new Aster were shorter than plants of the cultivar Karmijn.
  • 2. Plants of the new Aster were fuller and more rounded than plants of the cultivar Karmijn.

Plants of the new Aster can be compared to plants of the Aster cultivar Victoria Celeste, disclosed in U.S. Plant Pat. No. 13,333. In side-by-side comparisons conducted in Alva, Fla., plants of the new Aster differed from plants of the cultivar Victoria Celeste in the following characteristics:

• • 1. Plants of the new Aster were smaller and more mounding than plants of the cultivar Victoria Celeste.
  • 2. Plants of the new Aster flowered about four days earlier than plants of the cultivar Victoria Celeste when grown under natural season conditions.
  • 3. Plants of the new Aster had smaller inflorescences than plants of the cultivar Victoria Celeste.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in Pendleton, S.C. in an outdoor nursery and under conditions and practices which approximate those generally used in commercial potted Aster production. During the production of the plants, day temperatures averaged 32° C. and night temperatures averaged 21° C. Rooted cuttings were planted in 20 cm-containers, exposed to natural season conditions. Plants used in the photographs and for the description were about three months old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
