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 ‘G19FON01WH’.
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 is a naturally-occurring whole plant mutation of Chrysanthemum X morifilum ‘Fonti Pink’, not patented. The new Chrysanthemum plant was discovered and selected by the Invenntor as a single plant from within a population of plants of ‘Fonti Pink’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2016.
Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2017. 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
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G19FON01WH’. These characteristics in combination distinguish ‘G19FON01WH’ as a new and distinct Chrysanthemum plant:
1. Upright, outwardly spreading and uniformly rounded plant habit; 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. Decorative-type inflorescences with ray florets that are white in color.
Plants of the new Chrysanthemum can be compared to plants of the mutation parent, ‘Fonti Pink’. Plants of the new Chrysanthemum differ primarily from plants of ‘Fonti Pink’ in the following characteristics:
1. Plants of the new Chrysanthemum are more uniform than plants of ‘Fonti Pink’.
2. Ray florets of plants of the new Chrysanthemum are white in color whereas ray florets of plants of ‘Fonti Pink’ are pink in color.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘G19FON04YE’, disclosed in U.S. Plant patent application Ser. No. 15/732,910. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘G19FON04YE’ in ray floret color as ray florets of plants of the new Chrysanthemum are white in color whereas ray florets of plants of ‘G19FON04YE’ are yellow in color.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘G19FON11OR’, disclosed in U.S. Plant patent application Ser. No. 15/732,912. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘G19FON11OR’ in ray floret color as ray florets of plants of the new Chrysanthemum are white in color whereas ray florets of plants of ‘G19FON11OR’ are greyed orange in color.
Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum X morifolium ‘Amiko White’, disclosed in U.S. Plant Pat. No. 22,833. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Amiko White’ in the following characteristics:
1. Plants of the new Chrysanthemum are more uniformly rounded than plants of ‘Amiko White’.
2. Plants of the new Chrysanthemum flower about two to three weeks earlier than plants of ‘Amiko White’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant snowing me colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph comprises a side perspective view of a typical flowering plant of ‘G19FON01WH’ 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 detailed 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.
