USPP27259P2 - Leucanthemum plant named ‘Whoops-a-Daisy’ - Google Patents

Abstract

The new Shasta daisy plant, Leucanthemum ‘Whoops-a-Daisy’, is a sturdy plant with dark green serrated foliage and strong heavily-branched stems. The numerous inflorescences have ray tepals of near white developing to pale cream and cover the plant in a mound from the top of the plant to the ground. The new plant is useful in the landscape as a long-flowering border, in mass, as accent plants and containerized for patio or indoor use, or as a cut flower.

Description

Botanical classification: Leucanthemum×superbum (L. Burbank).

Variety denomination: ‘Whoops-a-Daisy’.

BACKGROUND OF THE INVENTION

The original Leucanthemum×superbum, or Shasta daisies, were bred by Luther Burbank in the late 1800's as a cross between Leucanthemum maximum (Ramond) DC. with Leucanthemum lacustre (Broth.) Samp. The new plant, Leucanthemum ‘Whoops-a-Daisy’ originated from a planned breeding program of the inventor, Kevin A. Hurd, at a wholesale perennial nursery in Zeeland, Mich., USA in the summer of 2009. The new Leucanthemum was a single selected seedling originally given the breeder number 09-25-01 as an open pollination of an unreleased proprietary female parent identified as 07-15-01 (not patented). The specific male parent is unknown. The present invention relates to a new and distinct cultivar of Shasta daisy botanically known as Leucanthemum×superbum and hereinafter referred to by the cultivar name ‘Whoops-a-Daisy’.

Asexual reproduction of the new cultivar by stem tip cuttings and shoot tip plant tissue culture at the same nursery in Zeeland, Mich. as early as the summer of 2011 has demonstrated that the new cultivar reproduces true to type with all of the characteristics of the original plant retained through successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new plant, Leucanthemum ‘Whoops-a-Daisy’, is most closely compared to the Leucanthemum ‘Sonnenschein’ (not patented) in flower and Leucanthemum ‘Snowcap’ (not patented) in habit. In test trials in Zeeland, Mich. Leucanthemum ‘Whoops-a-Daisy’ had a shorter, fuller, more compact, rounded habit in flower due to more numerous axillary branching than ‘Sonnenschein’. ‘Whoops-a-Daisy’ also has smaller diameter inflorescence than ‘Sonnenschein’ with ray tepals that are not as white as ‘Sonnenschein’. Compared to the female parent and grandparent, ‘Leukal 01’ U.S. Plant Pat. No. 15,204, the new plant has single, lighter colored ray tepals rather fringed, light-yellow, anemone-type flowers. ‘Whoops-a-Daisy’ is also shorter and more compact than either the female parent or ‘Leukal 01’. Other Shasta daisies similar in height include ‘Snowcap’ which is not as rounded or mounded in habit and has whiter ray tepals than ‘Whoops-a-Daisy’.

Leucanthemum ‘Whoops-a-Daisy’ differs from all cultivars known to the inventor in the following combined traits:

• • 1. Sturdy plants with dark green serrated foliage and strongly branched stems.
  • 2. Mounded habit with flowering from the top of the plant to the ground.
  • 3. Flowering with numerous axillary heads.
  • 4. Double row of ray tepals beginning near white and developing to pale cream.
    Table one below shows comparisons of other cultivars of Leucanthemum.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant has not been observed in all possible environments and conditions. The phenotype of Leucanthemum ‘Whoops-a-Daisy’ may vary with different growing conditions such as changes in temperature, light intensity, water availability, fertility, but without change in the genotype.
