Lily plant named Mona Lisa

Abstract

A lily plant named Mona Lisa principally characterized by its variegated flower color, with the petals being a generally mid-pink in the center, white along the edges and rebent tip, and a deep pink-red near its base and along the mid vein, with spot markings of similar color.

Description

The present invention comprises a new and distinct cultivar of lily, botanically known as lilium (Oriental hybrid) and hereinafter referred to by the cultivar name Mona Lisa.

Mona Lisa is a product of a planned breeding program, which had the primary objective of creating new lily cultivars with a new orange color, while retaining the desired characteristics of the parent cultivars.

Mona Lisa was originated from a hybridization made by the inventor Floris Vletter from a hybridization made in a controlled breeding program in Rijnsburg, The Netherlands in 1979. The female parent was a cultivar designated F 4431-77. The male parent of Mona Lisa was the cultivar Stargazer.

Mona Lisa was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor on June 22, 1982 in a controlled environment in Rijnsburg, The Netherlands.

The first act of asexual reproduction of Mona Lisa was accomplished when scales were taken by the inventor from the initial selection on Aug. 22, 1982 in a controlled environment in Rijnsburg, The Netherlands. Horticultural examination of selected units initiated Oct. 17, 1985 has demonstrated that the combination of characteristics as herein disclosed for Mona Lisa are firmly fixed and are retained through successive generations of asexual reproduction.

Mona Lisa 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. The following observations, measurements, and comparisons describe plants grown in Wageningen, The Netherlands under greenhouse conditions which approximate those generally used in commercial practice.

Mona Lisa is distinguished primarily by its medium pink flower color, with white edges and tips. The midvein, spot markings, and base areas of the petals are a deeper pinkish red. The flowers are medium to long and wide to very wide, with the petal types being substantially rebent.

The accompanying photographic drawing shows in top perspective view typical flower and foliage characteristics of Mona Lisa, with colors being as true as possible with illustrations of this type.

In the following description, color references are made to The Royal Horticultural Society Colour Chart.
