Abstract
A new and distinct cultivar of Leucanthemum plant named ‘Whitecap’, characterized by its relatively compact, upright and mounded plant habit; freely branching habit; strong and upright flowering stems; early, freely and continuous flowering habit; large single-type inflorescences with white-colored ray florets and large central yellow-colored disc; flower development that doesn't require vernalization; and good garden performance.
Description
Botanical designation: Leucanthemum x superbum.
Cultivar denomination: ‘WHITECAP’.
The present invention relates to a new and distinct cultivar of Leucanthemum plant, botanically known as Leucanthemum x superbum and hereinafter referred to by the name ‘Whitecap’.
The new Leucanthemum plant is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program is to create new Leucanthemum plants with a compact mounded habit, continuous flowering habit, numerous attractive single-type inflorescences and good garden performance.
The new Leucanthemum plant originated from an open-pollination in July, 2015 of Leucanthemum x superbum ‘White Magic’, disclosed in U.S. Plant Pat. No. 29,737, as the female, or seed, parent with an unknown selection of Leucanthemum x superbum as the male, or pollen, parent. The new Leucanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Arroyo Grande, Calif. in March, 2016.
Asexual reproduction of the new Leucanthemum plant by vegetative terminal cuttings in Arroyo Grande, Calif., since April, 2016 has shown that the unique features of this new Leucanthemum plant are stable and reproduced true to type in successive generations.
Plants of the new Leucanthemum 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 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 ‘Whitecap’. These characteristics in combination distinguish ‘Whitecap’ as a new and distinct Leucanthemum plant:
-
- 1. Relatively compact, upright and mounded plant habit.
- 2. Freely branching habit.
- 3. Strong and upright flowering stems.
- 4. Early, freely and continuous flowering habit.
- 5. Large single-type inflorescences with white-colored ray florets and large central yellow-colored disc.
- 6. No vernalization requirement for flowering.
- 7. Good garden performance.
Plants of the new Leucanthemum differ primarily from plants of the female parent, ‘White Magic’, in the following characteristics:
-
- 1. Plants of the new Leucanthemum are more compact and mounding than and not as tall and upright as plants of ‘White Magic’.
- 2. Plants of the new Leucanthemum have single-type inflorescences whereas plants of ‘White Magic’ have semi-double inflorescences.
Plants of the new Leucanthemum can be compared to plants of Leucanthemum x superbum ‘Snowcap’, not patented. In side-by-side comparisons, plants of the new Leucanthemum differ from plants of ‘Snowcap’ in the following characteristics:
-
- 1. Plants of the new Leucanthemum are more vigorous than plants of ‘Snowcap’.
- 2. Plants of the new Leucanthemum flower about two weeks earlier than plants of ‘Snowcap’.
- 3. Plants of the new Leucanthemum flower more continously than plants of ‘Snowcap’.
- 4. Plants of the new Leucanthemum have larger inflorescences than plants of ‘Snowcap’.
- 5. Plants of the new Leucanthemum do not require vernaliztation for flowering whereas plants of ‘Snowcap’ require vernalization for flowering.
- 6. Plants of the new Leucanthemum do not produce any detectable fragrance whereas plants of ‘Snowcap’ produce the foul fragrance typical of Leucanthemum plants.
Plants of the new Leucanthemum can also be compared to plants of Leucanthemum x superbum ‘Becky’, not patented. In side-by-side comparisons, plants of the new Leucanthemum differ from plants of ‘Becky’ in the following characteristics:
-
- 1. Plants of the new Leucanthemum are more vigorous than plants of ‘Becky’.
- 2. Plants of the new Leucanthemum flower about two weeks earlier than plants of ‘Becky’.
- 3. Plants of the new Leucanthemum have larger inflorescences than plants of ‘Becky’.
- 4. Plants of the new Leucanthemum do not require vernaliztation for flowering whereas plants of ‘Becky’ require vernalization for flowering.
- 5. Plants of the new Leucanthemum do not produce any detectable fragrance whereas plants of ‘Becky’ produce the foul fragrance typical of Leucanthemum plants.
The accompanying colored photographs illustrate the overall appearance of the new Leucanthemum plant 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 colors of the new Leucanthemum plant.
The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘Whitecap’ grown in a container.
The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘Whitecap’.
The aforementioned photographs and following observations and measurements describe plants grown in one-gallon containers during the spring in a glass-covered greenhouse in Elburn, Ill. and under cultural practices typical of commercial Leucanthemum production. During the production of the plants, day temperatures averaged 16° C., night temperatures averaged 13° C. and light levels averaged 2,500 foot-candles. Plants were 19 weeks old when the photographs were taken and 20 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
