Abstract

A new and distinct Leucanthemum plant having large inflorescences and light-yellow ray florets.

Description

Botanical classification: Chrysanthemum leucanthemum.
Varietal denomination: ‘Leukal 01’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Leucanthemum plant known by the varietal name ‘Leukal 01’. The new variety was discovered in 1999 in a selected breeding program in Tiefensee, Germany. The purpose of the breeding program was to discover a yellow-colored variety of Leucanthemum. The new variety originated as a single cultivar from a cross between ‘Christine Hagemaan’ (female parent, unpatented) and an unnamed, undistributed seedling (male parent, unpatented). The new variety blooms naturally in early June and has a compact growth habit with medium vigor similar to its parents, but, unlike ‘Leukal 01’, both parents exhibit white ray florets. Furthermore, ‘Leukal 01’ exhibits more distinct double flowering than both parents. The new variety begins to bloom around the same time and belongs in the same market category as ‘Kiemar’ (U.S. Plant Pat. No. 12,978). However, ‘Leukal 01’ has different colored ray florets, larger inflorescences and taller growth than ‘Kiemar’. The new variety was first asexually reproduced in 1999 by vegetative tip cuttings in Tiefensee, Germany. The new variety has been trial and field tested in Germany and has been found to retain its distinctive characteristics and remain true to type through successive propagations.
The following traits distinguish ‘Leukal 01’ as a new and distinct cultivar:
1. The ray florets of ‘Leukal 01’ are light yellow.
2. ‘Leukal 01’ exhibits numerous ray florets.
3. ‘Leukal 01’ exhibits a compact plant habit.
4. The inflorescences of ‘Leukal 01’ are long-lasting and large.
5. ‘Leukal 01’ blooms in early June.
DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawing illustrates a potted plant of the new variety, with the color being as nearly true as is possible with color illustrations of this type.
DESCRIPTION OF THE PLANT
The data which defines these characteristics were collected by asexual reproductions by cuttings carried out in Tiefensee, Germany. Plants were grown at temperatures of 15-22° Celcius in 20 cm pots with regular fertilizer of 15% Nitrogen—15% Phosphate—15% Potash. The color readings were taken under approximately 4000-7000 foot candles of artificial light. Plants were 12 months old when described. Color references are primarily to the 2001 R.H.S. Colour Chart of The Royal Horticultural Society of London.
