Abstract

A new and distinct cultivar of Lily plant named ‘Rousillon’ characterized by its erect to vertical flowers, intense purple-red color with contrasting orange pollen and stripes, spots and flakes on the inner side of the throat, and vigorous growth.

Description

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of lily plant, botanically known as Lilium l., and hereinafter referred to by the cultivar name ‘Rousillon’.

‘Rousillon’ is a product of a planned breeding program which had the objective of creating new lily cultivars having many large erect flowers and vigorous growth.

‘Rousillon’ was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, the Netherlands in 1992. The male and female parents were unnamed seedlings of Lilium l. oriental hybrids. Both parents are proprietary cultivars used in the breeding program.

‘Rousillon’ was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor, Cees A. van der Voort, in the months of May and June 1992 in a controlled environment in Rijnsburg, the Netherlands.

The first act of asexual reproduction of ‘Rousillon’ was accomplished when scales were taken from the initial selection in October 1994 in a controlled environment in Rijnsburg, the Netherlands by, or under the supervision of, Cees A. van der Voort. Horticultural examination of selected units initiated in May, 1994 has demonstrated that the combination of characteristics as herein disclosed for ‘Rousillon’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Rousillon’ which in combination distinguish this lily as a new and distinct cultivar:

1. large flowers;

2. erect to vertical flowers arranged in a longitudinal axis;

3. red-purple color with contrasting orange pollen and marking and spots on the inner side of the throat; and

4. vigorous growth habit.

‘Rousillon’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in genotype. The following observations, measurements, and comparisons describe plants grown in the experimental research station CPRO-DLO, Wageningen, the Netherlands under conditions which approximate those generally used in commercial practice.

Of the many commercial cultivars known to the present inventor, no other cultivars are similar in comparison to ‘Rousillon’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustration shows typical plant and flower characteristics of ‘Rousillon’, with colors being as true as possible with illustrations of this type.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society (R.H.S) Colour Chart. The color values were determined between 12 pm and 2 pm in June 1999 at the experimental research station CPRO-DLO, Wageningen, the Netherlands.

The age of the described plant is between 100-120 days after planting the bulbs. The instant plant was grown between 12/13° C. and 17/18° C. greenhouse. The average daylight during cultivation from April to July was 12-18 hours per day. Fertilizers like Fe and Ca are applied depending on the conditions of the soil in which the bulbs are planted. Average watering rate is 2 times 5 min. per day during the cultivation period. The quantity of irrigation strongly depends on the outside temperatures and light levels.
