Lily plant named Pesaro

Abstract

A new lily plant named Pesaro, characterized by its very large flowers, very tall plant height, vigorous growth habit, pink flower color with many darker red-pink spots and white near base, strongly curved petals, and its contrasting orange pollen.

Description

The present invention comprises a new and distinct cultivar of lily, botanically known as Lilium, commercially known as Lilium oriental hybrid, and hereinafter referred to by the cultivar name Pesaro. The parents were oriental varieties belonging to division VII(b) 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 objective of creating new lily cultivars with distinctive pink color, long firm stems, and good forcing characteristics.

The new cultivar was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, The Netherlands in 1981. Both the male and female parents were unnamed seedlings.

The new cultivar was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in July 1981 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 1985 in a controlled environment in Rijnsburg, The Netherlands.

Horticultural examination of selected units has demonstrated that the combination of characteristics as herein disclosed for Pesaro 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 significantly with variations in environment such as temperature, light intensity, and day length, without, however, any variation in 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 large flowers;

2. Pink flower color with many dark red-purple spots or markings, and white near base;

3. Strongly curved petals;

4. Orange pollen pleasantly contrasts with flower color.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new cultivar is Stargazer. In comparison to Stargazer, Pesaro has longer stems and a more intense pink flower color. When flowering is forced under natural light, Pesaro produces an inflorescence approximately 6 days earlier than Stargazer, under the same growing conditions. Pesaro is fertile.

The accompanying photographic drawing shows typical flower characteristics of the new cultivar, with colors being as true as possible with illustrations of this type. The photograph comprises a top perspective view several flowers open and buds at various stages.

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