Abstract

A distinct cultivar of Leucanthemum plant named ‘Kiemar’, characterized by its upright, compact and uniform plant habit; dark green foliage; early flowering habit; daisy-type inflorescences; white-colored ray florets and bright yellow-colored disc florets; and good garden performance.

Description

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Leucanthemum plant, botanically known as Chrysanthemum leucanthemum and hereinafter referred to by the name ‘Kiemar’.
The new Leucanthemum is a product of a planned breeding program conducted by the Inventor in Steenbergen, The Netherlands. The objective of the breeding program is to create compact Leucanthemum cultivars that flower early and have good garden performance.
The new Leucanthemum originated from a cross made by the Inventor in the summer of 1993, in Steenbergen, The Netherlands, of two unidentified seedling selections of Chrysanthemum leucanthemum. The new Leucanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Steenbergen, The Netherlands in the summer of 1995. The selection of this plant was based on its compact plant habit and early flowering.
Asexual reproduction of the new Leucanthemum by vegetative tip cuttings was first conducted in Steenbergen, The Netherlands in 1997. Asexual reproduction by cuttings has shown that the unique features of this new Leucanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Kiemar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kiemar’. These characteristics in combination distinguish ‘Kiemar’ as a new and distinct Leucanthemum:
1. Upright, compact and uniform plant habit.
2. Dark green foliage.
3. Early flowering.
4. Daisy-type inflorescences that are about 5 cm in diameter.
5. White-colored ray florets and bright yellow-colored disc florets.
6. Good garden performance.
Plants of the new Leucanthemum have been observed to be more compact and stronger than plants of the parent selections.
Plants of the new Leucanthemum can be compared to plants of the seed-propagated Leucanthemum cultivar White Knight not patented. In side-by-side comparisons conducted by the Inventor in Steenbergen, The Netherlands, plants of the new Leucanthemum differ from plants of the cultivar White Knight in the following characteristics:
1. Plants of the new Leucanthemum flower about three weeks earlier than plants of the cultivar White Knight.
2. Plants of the new Leucanthemum are stronger than plants of the cultivar White Knight.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Leucanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Leucanthemum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Kiemar’.
The photograph at the bottom of the sheet comprises a close-up view of typical developing inflorescences and leaves of ‘Kiemar’. Plants used in the photographs were about 10 weeks from planting unrooted cuttings.
DETAILED BOTANICAL DESCRIPTION
The cultivar Kiemar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, water status, and fertilizer rates without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in Lompoc, Calif., under commercial practice during the winter in a polycarbonate-covered greenhouse with day temperatures about 18 to 24° C., night temperatures about 16 to 18° C. and light levels about 4,000 to 8,000 foot-candles. Unrooted cuttings were directly planted in 15-cm containers and grown for about 10 weeks.
