Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Mona Lisa Splendid’, characterized by its decorative anemone-type inflorsecences with elliptic-shaped, light purple-colored ray florets and green-colored enlarged disc florets; strong and upright flowering stems; freely flowering habit; early and uniform flowering response; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Mona Lisa Splendid’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a cut flower and hereinafter referred to by the name ‘Mona Lisa Splendid’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Mona Lisa Dark Pink, not patented. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within a population of plants of the cultivar in May, 2004, in Hensbroek, The Netherlands. The selection of this plant was based on its attractive ray floret color and good inflorescence form.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Hensbroek, The Netherlands since July, 2004, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Mona Lisa Splendid 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 ‘Mona Lisa Splendid’. These characteristics in combination distinguish ‘Mona Lisa Splendid’ as a new and distinct cultivar of Chrysanthemum:

- 1. Decorative anemone-type inflorescences with elliptic-shaped, light purple-colored ray florets and green-colored enlarged disc florets; typically grown as a spray-type.
- 2. Strong and upright flowering stems.
- 3. Freely flowering habit.
- 4. Early and uniform flowering response; plants flower about seven weeks after the start of photoinductive treatments.
- 5. Good postproduction longevity; plants maintain good substance for about three weeks in an interior environment.

Plants of the new Chrysanthemum differ from plants of the parent, the cultivar Mona Lisa Dark Pink, primarily in ray floret color.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Mona Lisa Rosy, disclosed in U.S. Plant patent application Ser. No. 11/259,312. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the cultivar Mona Lisa Rosy in the following characteristics:

- 1. Plants of the new Chrysanthemum had darker green-colored leaves than plants of the cultivar Mona Lisa Rosy.
- 2. Plants of the new Chrysanthemum were more freely flowering than plants of the cultivar Mona Lisa Rosy.
- 3. Plants of the new Chrysanthemum and the cultivar Mona Lisa Rosy differed in ray floret color.
- 4. Plants of the new Chrysanthemum had longer peduncles than plants of the cultivar Mona Lisa Rosy.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum. These photographs show 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 Chrysanthemum.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering stem of ‘Mona Lisa Splendid’ grown as a natural spray.

The photograph at the bottom of the sheet is a close-up view of a typical flowering stem of ‘Mona Lisa Splendid’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown during the winter in Hensbroek, 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. During the production of the plants, day temperatures ranged from 17.5° C. to 30° C., night temperatures ranged from 18.5° C. to 24° C. and light levels were about five kilolux. Plants were pinched once and were about eleven weeks from planting when the photographs and the description were taken.

Botanical classification: Chrysanthemum×morifolium cultivar Mona Lisa Splendid.
Parentage: Naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Mona Lisa Dark Pink, not patented.
Propagation:
- - Type.—Terminal vegetative cuttings.
  - Time to initiate roots.—About six to seven days with temperatures about 20° C.
  - Time to produce a rooted young plant.—About 14 to 16 days with temperatures about 20° C.
  - Root description/habit.—Fine; light brown in color; freely branching.
Plant description:
- - Appearance.—Herbaceous decorative anemone-type cut flower that is typically grown as a natural spray.
  - Flowering stem description.—Aspect: Erect. Length: About 75 cm. Diameter: About 6 mm. Texture: Pubescent; longitudinally ridged. Color: 146A.
  - Foliage description.—Arrangement: Alternate; simple. Length: About 7 cm to 12 cm. Width: About 5 cm to 7.5 cm. Apex: Apiculate. Base: Attenuate. Margin: Palmately lobed. Texture, upper and lower surfaces: Pubescent, rough; veins prominent on lower surface. Color: Developing and fully expanded foliage, upper surface: Close to 139A; venation, close to 147B.

Inflorescence description:
- - Appearance.—Decorative anemone-type inflorescence form with elliptic-shaped ray florets and enlarged disc florets. Inflorescences borne on terminals, arising from leaf axils. Ray and disc florets develop acropetally on a capitulum. Inflorescences not fragrant.

At other times of the year, inflorescence initiation and development can be induced under short day/long night conditions (at least 13.5 hours of darkness). Early and uniform flowering response; plants exposed to two weeks of long day/short night conditions after planting followed by photoinductive short day/long night conditions flower about seven weeks later when grown as a natural spray.
