Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Anastasia Green’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and referred to by the name ‘Anastasia Green’.

The new Chrysanthemum was discovered and selected by the Inventor in a controlled environment in 's-Gravenzande, The Netherlands, as a naturally-occurring whole plant mutation of the Chrysanthemum cultivar Anastasia, disclosed in U.S. Plant Pat. No. 13,550. The new plant was discovered within a population of plants of the cultivar Anastasia and was selected on the basis of its unique green-colored ray florets.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in 's-Gravenzande, The Netherlands since May, 2004, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar Anastasia Green has 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 ‘Anastasia Green’. These characteristics in combination distinguish ‘Anastasia Green’ as a new and distinct cultivar:

    • 1. Large quilled spider double-type inflorescences with green-colored ray florets; typically grown as a disbudded type with a single inflorescence per flowering stem.
    • 2. Numerous ray florets and very few disc florets; disc florets typically inconspicuous.
    • 3. Dark green-colored foliage.
    • 4. Strong and upright flowering stems.
    • 5. Low number of lateral branches which reduces the amount of disbudding required.
    • 6. Short response time.
    • 7. Excellent postproduction longevity.

Plants of the new Chrysanthemum are most similar to plants of the parent cultivar Anastasia. In side-by-side comparisons conducted by the Inventor in 's-Gravenzande, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the cultivar Anastasia in ray floret coloration as plants of the cultivar Anastasia had white-colored ray florets. In addition, ray florets of plants of the new Chrysanthemum are curved at the apices whereas ray florets of plants of the cultivar Anastasia are straight at the apices.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 actual colors of the new Chrysanthemum.

The photograph at the top of the sheet comprises a top perspective view of a typical flowering stem of ‘Anastasia Green’.

The photograph at the bottom of the sheet comprises a close-up view of the upper and lower surfaces of typical leaves of ‘Anastasia Green’.

 DETAILED BOTANICAL DESCRIPTION

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. The aforementioned photographs and following observations and measurements describe plants grown in 's-Gravenzande, The Netherlands, under commercial practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. Average day and night temperatures were 18° C. and 19° C., respectively. Plants were not pinched and were grown as single-stem disbud types.

  • Botanical classification: Chrysanthemum×morifolium cultivar Anastasia Green.
  • Commercial classification: Quilled spider double-type Chrysanthemum typically grown as a disbudded cut flower.
  • Parentage: Naturally-occurring whole plant mutation of Chrysanthemum×morifolium cultivar Anastasia, disclosed in U.S. Plant Pat. No. 13,550.
  • Propagation:
      • Type.—Terminal tip cuttings.
      • Time to initiate roots, summer.—About 10 days at 20° C.
      • Time to initiate roots, winter.—About 14 days at 20° C.
      • Root description.—Fine, fibrous and well-branched.
  • Plant description:
      • Appearance.—Herbaceous quilled spider double-type cut Chrysanthemum; typically grown as a single-stem and as a disbudded type with one single inflorescence per flowering stem. Upright and strong flowering stems.
      • Growth rate.—Moderate; moderately vigorous.
      • Crop time.—For cut flowers, about 78 and 124 days are required to produce flowering stems during the summer and winter, respectively.
      • Flowering stem description.—Length: About 80 to 90 cm. Diameter, as apex: About 6.5 mm. Strength: Strong. Aspect: Upright. Branching habit: Plants are typically grown as single stems, but if pinched, will develop 10 to 15 lateral stems. Color: 146B.
      • Foliage description.—Arrangement: Alternate. Quantity of leaves per main stem: About 20 to 25. Length: About 8 to 13 cm. Width: About 4 to 9 cm. Apex: Broadly acuminate. Base: Attenuate. Margin: Palmately lobed. Texture, upper and lower surfaces: Rough; pubescent. Petiole length: About 1 to 3 cm. Color: Developing foliage, upper surface: 147A. Developing foliage, lower surface: Closest to 147B. Fully expanded, upper surface: 147A. Fully expanded, lower surface: 137A. Venation, upper surface: 137B. Venation, lower surface: 146B. Petiole, upper and lower surfaces: 147B.
  • Inflorescence description:
      • Appearance.—Quilled spider double-type inflorescence form. Inflorescences borne on terminals, arising from leaf axils. Ray and disc florets develop acropetally on the receptacle.
      • Flowering response.—Under natural conditions, plants typically flower in November in the Northern Hemisphere. At other times of the year, inflorescence initiation and development can be induced under short day/long night conditions (at least 13 hours of darkness). Plants exposed to long day/short night conditions after planting followed by photoinductive short day/long night conditions flower about eight weeks later.
      • Postproduction longevity.—Inflorescences will maintain good substance and form for about 3.5 weeks after harvesting.
      • Quantity of inflorescences per flowering stem.—Grown as a disbud type, all lateral inflorescences are removed and only the terminal inflorescence develops. If lateral inflorescences are not removed, about 8 to 11 inflorescences per flowering stem will develop.
      • Inflorescence size.—Diameter: Large, about 12 to 14 cm. Depth (height): About 4 to 5 cm. Diameter of disc: About 1.2 cm; inconspicuous.

      • Peduncles.—Length, terminal peduncle: About 3 to 4 cm. Length, fourth peduncle: About 4 to 5 cm. Diameter: About 4 to 5 mm. Texture: Pubescent. Color: 147B.
      • Reproductive organs.—Androecium: Present on disc florets only. Anther color: 15B. Amount of pollen: Moderate. Pollen: 16B. Gynoecium: Present on both ray and disc florets. Stigma length: About 5 mm. Stigma width: About 0.5 mm. Stigma color: Towards the apex, 9C; towards the base, close to 155C.
