Abstract

A new and distinct cultivar of Leucanthemum superbum plant named ‘DLEULUCGRC’ is disclosed, characterized by an upright, compact plant habit and single daisy flowers. Vernalization is not required. Plants exhibit good heat tolerance. The new variety is a Leucanthemum useful for ornamental garden and container uses.

Description

Latin name of the genus and species: Leucanthemum superbum.
Variety denomination: ‘DLEULUCGRC’.
BACKGROUND OF THE INVENTION
The new cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Leucanthemum varieties with good heat tolerance and not requiring vernalization. The open pollination resulting in this new variety was made during April of 2012.
Asexual reproduction of the new cultivar ‘DLEULUCGRC’ was first performed in March of 2014, by basal vegetative cuttings at a greenhouse in Moshav Mishmar Hashiva, Israel. All subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘DLEULUCGRC’ These characteristics in combination distinguish ‘DLEULUCGRC’ as a new and distinct Leucanthemum cultivar:
    • 1. Vernalization not required for flowering.
    • 2. Good heat tolerance.
PARENT COMPARISON
Plants of the new cultivar ‘DLEULUCGRC’ are similar to plants of the parent variety, Leucanthemum ‘LK-9-19’ in most horticultural characteristics, however, plants of ‘DLEULUCGRC’ differ in the following ways:
    • 1. ‘DLEULUCGRC’ begins flowering later than the seed parent variety.
    • 2. ‘DLEULUCGRC’ is more heat tolerant than the seed parent.
COMMERCIAL COMPARISON
Plants of the new cultivar ‘DLEULUCGRC’ are similar to plants of the commercial variety Leucanthemum ‘Snowcap’, unpatented, in most horticultural characteristics. Plants of the new cultivar ‘DLEULUCGRC’, however, differ in the following:
    • 1. ‘DLEULUCGRC’ does not require vernalization to induce flowering, ‘Snowcap’ requires vernalization to begin flowering.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DLEULUCGRC’ grown in a greenhouse. The pot size is a commercial 12 cm container. The plant shown is approximately 20 weeks old.
FIG. 2 illustrates a close-up view of the inflorescence.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
