Description

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘VENOS YELLOW’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘Venos Yellow’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in September, 2011 of Chrysanthemum X morifolium ‘Axima Yellow’, not patented, as the female, or seed, parent with Chrysanthemum X morifolium ‘Cortona’, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2012.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2015. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum 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, 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 ‘Venos Yellow’. These characteristics in combination distinguish ‘Venos Yellow’ as a new and distinct Chrysanthemum plant:

    • 1. Upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit.
    • 2. Freely branching habit; dense and full plant habit.
    • 3. Dark green-colored leaves.
    • 4. Uniform and freely flowering habit.
    • 5. Long flowering period.
    • 6. Relatively large decorative-type inflorescences with dark yellow-colored ray florets.

Plants of the new Chrysanthemum differ from the female parent, ‘Axima Yellow’, in the following characteristics:

    • 1. Plants of the new Chrysanthemum are more uniform in plant shape than plants of ‘Axima Yellow’.
    • 2. Plants of the new Chrysanthemum flower later than plants of ‘Axima Yellow’.
    • 3. Ray florets of plants of the new Chrysanthemum are slightly lighter yellow in color than ray florets of plants of ‘Axima Yellow’.

Plants of the new Chrysanthemum differ from the male parent, ‘Cortona’, in the following characteristics:

    • 1. Plants of the new Chrysanthemum are more uniform in plant shape than plants of ‘Cortona’.
    • 2. Inflorescences of plants of the new Chrysanthemum are fully decorative in form whereas inflorescences of plants of ‘Cortona’ are semi-decorative in form.
    • 3. Ray florets of plants of the new Chrysanthemum are lighter yellow in color than ray florets of plants of ‘Cortona’.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘Allegra Yellow’, disclosed in U.S. Plant Pat. No. 21,785. In side-by-side comparisons, plants of the new Chrysanthemum differ from plants of ‘Allegra Yellow’ in the following characteristics:

    • 1. Plants of the new Chrysanthemum are more spherical than and not as flat as plants of ‘Allegra Yellow’.
    • 2. Plants of the new Chrysanthemum flower later than plants of ‘Allegra Yellow’.
    • 3. Inflorescences of plants of the new Chrysanthemum are longer lasting than inflorescences of plants of ‘Allegra Yellow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

The photograph comprises a side perspective view of a typical flowering plant of ‘Venos Yellow’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer and autumn and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 25° C. and night temperatures ranged from 12° C. to 18° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
