Lily plant named Gibraltar

Abstract

A new and distinct cultivar of Lily plant named Gibraltar, characterized by its intense orange flower color, large flowers, long stems, vigorous growth habit, and floriferous habit.

Description

The present invention comprises a new and distinct cultivar of Lily, botanically known as Lilium, known commercially as Lilium Asiatic hybrid, and hereinafter referred to by the cultivar name Gibraltar. The parents were asiatic varieties belonging to division I described in "Classification of Lily Cultivars into Divisions" published by Victoria Mathews, The Royal Botanic Gardens, Kew (1989).

The new cultivar is a product of a planned breeding program which had the primary objectives of creating new Lily cultivars with long flexible stems, orange flower color and floriferous habit.

The new cultivar was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, The Netherlands in 1984. Both the male and the female parents are unnamed seedlings.

The new cultivar was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in June 1984 in a controlled environment in Rijnsburg, The Netherlands.

The first act of asexual reproduction of the new cultivar was accomplished by the inventor when scales were taken from the initial selection in 1987 in a controlled environment in Rijnsburg, The Netherlands.

Horticultural examination of selected units has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.

The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, and day length, without, however, varying the genotype. The following observations, measurements and comparisons describe plants grown in Wageningen and Rijnsburg, The Netherlands under greenhouse conditions which approximate those generally used in commercial practice.

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

1. Very vigorous growth habit;

2. Strong flower stems;

3. Intense orange flower color;

4. Floriferous habit.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new cultivar is the cultivar Eurovision. In comparison to Eurovision, Gibraltar has larger flowers, more intense orange flower color, and longer stems.

The accompanying photographic drawing shows typical flower characteristics of the new cultivar, with colors being as true as possible with illustrations of this type. When flowering is forced under natural light, Gibraltar produces an inflorescence approximately 41 days earlier than Stargazer, grown under the same conditions. Gibraltar is fertile. The photograph comprises a front perspective of flowers fully open, and several buds in various stages.

In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Color Chart. The colour values were determined at Wageningen in 1988-1989 and at Rijnsburg in July 1991.
