Abstract

A new and distinct cultivar of Lily plant named ‘Sorbonne’ characterized by having soft, pinkish-red color, white flower tips, upright flowers, and vigorous growth habit.

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 ‘Sorbonne’.

‘Sorbonne’ is a product of a planned breeding program which had the objective of creating new lily cultivars having large, upright flowers.

‘Sorbonne’ was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, the Netherlands in 1985. The male and female parents were unnamed seedlings of Lilium L. oriental hybrids. Both parents are proprietary cultivars used in the breeding program.

‘Sorbonne’ was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor, Cees A. van der Voort, on Jun. 7, 1988 in a controlled environment in Rijnsburg, the Netherlands.

The first act of asexual reproduction of ‘Sorbonne’ was accomplished when scales were taken from the initial selection in October 1988 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, 1988 has demonstrated that the combination of characteristics as herein disclosed for ‘Sorbonne’ 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 ‘Sorbonne’ which in combination distinguish this lily as a new and distinct cultivar:

• • 1. soft, pinkish red-color;
  • 2. white flower tips;
  • 3. upright flowers; and
  • 4. vigorous growth habit.

‘Sorbonne’ 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 values describe the new cultivar as 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 ‘Sorbonne’.

BRIEF DESCRIPTION OF THE DRAWING

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

DETAILED BOTANICAL DESCRIPTION
