Title: Leucanthemum Plant Named ‘SUNRIMAIZY’
Inventor: Scott C. Trees
Filed: Concurrently with the instant application
BACKGROUND OF THE INVENTION
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 ‘Sunrimaiapy’.
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 inflorescences, no vernalization requirement for flowering, good garden performance and good winter hardiness.
The new Leucanthemum plant originated from an open-pollination in August, 2016 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 August, 2017.
Asexual reproduction of the new Leucanthemum plant by vegetative terminal cuttings in Arroyo Grande, Calif., since August, 2017 has shown that the unique features of this new Leucanthemum plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
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 ‘Sunrimaiapy’. These characteristics in combination distinguish ‘Sunrimaiapy’ as a new and distinct Leucanthemum plant:
    • 1. Relatively compact, upright and mounded plant habit.
    • 2. Freely branching habit.
    • 3. Strong flowering stems.
    • 4. Early and freely flowering habit; long flowering period.
    • 5. Large single-type inflorescences with white-colored ray florets and bright yellow-colored disc florets.
    • 6. No vernalization requirement for flowering.
    • 7. Good garden performance and winter hardiness.
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 plants of ‘White Magic’.
    • 2. Plants of the new Leucanthemum are more freely branching than plants of ‘White Magic’.
    • 3. Leaves of plants of the new Leucanthemum are darker green in color than leaves of plants of ‘White Magic’.
    • 4. Plants of the new Leucanthemum flower more consistently and longer than plants of ‘White Magic’.
Plants of the new Leucanthemum can be compared to plants of Leucanthemum x superbum ‘Sunrimaizy’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Leucanthemum differs from plants of ‘Sunrimaizy’ in the following characteristics:
    • 1. Plants of the new Leucanthemum are shorter and have shorter internodes than plants of ‘Sunrimaizy’.
    • 2. Plants of the new Leucanthemum have smaller leaves than plants of ‘Sunrimaizy’.
    • 3. Plants of the new Leucanthemum have more inflorescences per plant than plants of ‘Sunrimaizy’.
    • 4. Plants of the new Leucanthemum have single-type inflorescences whereas plants of ‘Sunrimaizy’ have semi-double to double-type inflorescences.
Plants of the new Leucanthemum can be compared to plants of Leucanthemum x superbum ‘Crazy Daisy’, not patented. In side-by-side comparisons, plants of the new Leucanthemum differ from plants of ‘Crazy Daisy’ in the following characteristics:
    • 1. Plants of the new Leucanthemum are more compact and mounding than plants of ‘Crazy Daisy’.
    • 2. Plants of the new Leucanthemum have single-type inflorescences whereas plants of ‘Crazy Daisy’ have double-type inflorescences.
    • 3. Ray florets of plants of the new Leucanthemum are flatter and not as twisting as ray florets of plants of ‘Crazy Daisy’.
    • 4. Plants of the new Leucanthemum do not require vernalization for flowering whereas plants of ‘Crazy Daisy’ require vernalization for flowering.
    • 5. Plants of the new Leucanthemum do not produce any detectable fragrance whereas plants of ‘Crazy Daisy’ produce the pungent and 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 have darker green-colored leaves than plants of ‘Becky’.
    • 2. Plants of the new Leucanthemum have single-type inflorescences whereas plants of ‘Becky’ have semi-double type inflorescences.
    • 3. Plants of the new Leucanthemum flower for a longer period of time plants of ‘Becky’.
    • 4. Plants of the new Leucanthemum do not require vernalization 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 pungent and foul fragrance typical of Leucanthemum plants.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 ‘Sunrimaiapy’ grown in a container.
