Lily plant named ‘Sunny Keys’

Abstract

A new and distinct cultivar of Lily plant named ‘Sunny Keys’, characterized by its compact and upright plant habit; vigorous growth habit; freely flowering habit; upright flower buds; red purple-colored flowers; and good postproduction longevity.

Description

Botanical designation: Lilium hybrida.

Cultivar denomination: ‘SUNNY KEYS’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lily plant, commercially known as Oriental Hybrid Lily, botanically known as Lilium hybrida and hereinafter referred to by the name ‘Sunny Keys’.

The new Oriental Hybrid Lily plant is a product of a planned breeding program conducted by the Inventor in Wieringerwerf, The Netherlands. The objective of the breeding program is to develop new compact potted Oriental Hybrid Lily plants with healthy foliage, large attractive flowers and good postproduction longevity.

The new Oriental Hybrid Lily plant originated from a cross-pollination in 2003 of two unnamed proprietary seedling selections of Lilium hybrida, not patented. The new Oriental Hybrid Lily plant was discovered and selected by the Inventor as a single flowering plant from within the resultant progeny of the stated cross-pollination in a controlled greenhouse environment in Wieringerwerf, The Netherlands in 2006.

Asexual reproduction of the new Oriental Hybrid Lily plant by bulb scales in a controlled greenhouse environment in Wieringerwerf, The Netherlands since 2009 has shown that the unique features of this new Oriental Hybrid Lily plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Oriental Hybrid Lily have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunny Keys’. These characteristics in combination distinguish ‘Sunny Keys’ as a new and distinct Oriental Hybrid Lily plant:

• • 1. Compact and upright plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely flowering habit.
  • 4. Upright flower buds.
  • 5. Red purple-colored flowers.
  • 6. Good postproduction longevity.

Plants of the new Oriental Hybrid Lily differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Oriental Hybrid Lily are more compact than plants of the female parent selection.
  • 2. Plants of the new Oriental Hybrid Lily and the female parent selection differ in flower bud and flower color.

Plants of the new Oriental Hybrid Lily differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Oriental Hybrid Lily are more compact than plants of the male parent selection.
  • 2. Plants of the new Oriental Hybrid Lily have broader leaves than plants of the male parent selection.
  • 3. Plants of the new Oriental Hybrid Lily have smaller flowers than plants of the male parent selection.

Plants of the new Oriental Hybrid Lily can be compared to plants of the Oriental Hybrid Lily ‘After Eight’, not patented. Plants of the new Oriental Hybrid Lily differ from plants of ‘After Eight’ in the following characteristics:

• • 1. Plants of the new Oriental Hybrid Lily have darker green-colored leaves than plants of ‘After Eight’.
  • 2. Plants of the new Oriental Hybrid Lily flower later than plants of ‘After Eight’.
  • 3. Plants of the new Oriental Hybrid Lily have smaller flowers than plants of ‘After Eight’.
  • 4. Plants of the new Oriental Hybrid Lily and ‘After Eight’ differ in flower color as plants of ‘After Eight’ have dark pink-colored flowers.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Oriental Hybrid Lily plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Oriental Hybrid Lily plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Sunny Keys’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring in 15-cm containers in a glass-covered greenhouse in Wieringerwerf, The Netherlands and under cultural practices typically used in Oriental Hybrid Lily commercial production. During the production of the plants, day temperatures averaged 18° C., night temperatures averaged 15° C. and light levels averaged 6,000 lux. Measurements and numerical values represent averages for typical flowering plants. Plants were 110 days old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
