Description

Botanical designation: Syringa meyeri×Syringa microphylla.

Cultivar denomination: ‘PINK PERFUME’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lilac plant, botanically known as Syringa meyeri×Syringa microphylla and hereinafter referred to by the name ‘Pink Perfume’.

The new Lilac plant is a product of a planned breeding program conducted by the Inventor in Zundert, The Netherlands. The objective of the breeding program is to create new Lilac plants with fragrant flowers and repeat flowering habit.

The new Lilac plant originated from a cross-pollination conducted by the Inventor in 2000 of Syringa meyeri ‘Palibin’, not patented, as the female, or seed, parent with Syringa microphylla ‘Superba’, not patented, as the male, or pollen, parent. The new Lilac plant was discovered and selected by the Inventor during the summer of 2003 as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Zundert, The Netherlands.

Asexual reproduction of the new Lilac plant by softwood cuttings in a controlled greenhouse environment in Zundert, The Netherlands since 2004 has shown that the unique features of this new Lilac plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Lilac have not been observed under all possible 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 ‘Pink Perfume’. These characteristics in combination distinguish ‘Pink Perfume’ as a new and distinct Lilac plant:

    • 1. Relatively compact, upright and somewhat outwardly spreading plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Large inflorescences with strongly fragrant pink-colored flowers that are not persistent.
    • 6. Long and repeat flowering habit.
    • 7. Good cold hardiness.

Plants of the new Lilac can be compared to plants of the female parent, ‘Palibin’. Plants of the new Lilac differ primarily from plants of ‘Palibin’ in the following characteristics:

    • 1. Plants of the new Lilac are larger than plants of ‘Palibin’.
    • 2. Plants of the new Lilac are more freely flowering and flower for a longer period of time than plants of ‘Palibin’.
    • 3. Plants of the new Lilac have larger inflorescences than plants of ‘Palibin’.

Plants of the new Lilac can be compared to plants of the male parent, ‘Superba’. Plants of the new Lilac differ primarily from plants of ‘Superba’ in the following characteristics:

    • 1. Plants of the new Lilac are more compact than and not as open as plants of ‘Superba’.
    • 2. Plants of the new Lilac flower for a longer period of time than plants of ‘Superba’.
    • 3. Plants of the new Lilac have larger inflorescences than plants of ‘Superba’.
    • 4. Flowers of plants of the new Lilac were more fragrant than flowers of plants of ‘Superba’.

Plants of the new Lilac can be also compared to plants of the Syringa hybrida ‘Penda’, disclosed in U.S. Plant Pat. No. 20,575. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Lilac differed primarily from plants of ‘Penda’ in the following characteristics:

    • 1. Plants of the new Lilac were more compact than and were not as open as plants of ‘Penda’.
    • 2. Plants of the new Lilac had larger inflorescences than plants of ‘Penda’.
    • 3. Flowers of plants of the new Lilac and ‘Penda’ differed in flower color as plants of ‘Penda’ had purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet is a side perspective view of a flowering typical plant of ‘Pink Perfume’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Pink Perfume’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in an outdoor nursery in Grand Haven, Mich. under cultural practices which closely approximate commercial production. During the production of the plants, day temperatures ranged from 12° C. to 25° C. and night temperatures ranged from 4° C. to 14° C. Plants were five years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
