Abstract: A new and distinct cultivar of Viburnum plant named `Lisarose`, characterized by its broadly upright plant habit; moderately vigorous growth habit; freely branching habit; numerous pink and white-colored flowers; and good garden performance.
Claim: It is claimed:

1. A new and distinct Viburnum plant named `Lisarose` as illustrated and described.
Description: Botanical designation: Viburnumtinus.

Cultivar denomination: `LISAROSE`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Viburnum plant, botanically known as Viburnum tinus and hereinafter referred to by the name `Lisarose`.

The new Viburnum plant originated from an open-pollination in 2003 of an unnamed seedling selection of Viburnum tinus, not patented, as the female, or seed, parent with an unknown selection of Viburnum tinus as the male, or pollen, parent. Thenew Viburnum plant was discovered and selected by the Inventor in 2005 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Ardon, France.

Asexual reproduction of the new Viburnum plant by softwood cuttings in a controlled environment in Ardon, France since 2005 has shown that the unique features of this new Viburnum plant are stable and reproduced true to type in successivegenerations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Viburnum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 `Lisarose`. These characteristics in combination distinguish `Lisarose` as a new and distinct cultivar of Viburnum plant: 1. Broadlyupright plant habit. 2. Moderately vigorous growth habit. 3. Freely branching habit. 4. Numerous pink and white-colored flowers. 5. Good garden performance.

Plants of the new Viburnum can be compared to plants of the female parent selection. Plants of the new Viburnum differ from plants of the female parent selection in the following characteristics: 1. Leaves of plants of the new Viburnum areglossier than leaves of plants of the female parent selection. 2. Plants of the new Viburnum have darker pink-colored flower buds than plants of the female parent selection. 3. Plants of the new Viburnum are more freely flowering than plants of thefemale parent selection.

Plants of the new Viburnum can be compared to plants of Viburnum tinus `Gwenllian`, not patented. Plants of the new Viburnum differ from plants of `Gwenllian` in the following characteristics: 1. Leaves of plants of the new Viburnum areglossier than leaves of plants of `Gwenllian`. 2. Plants of the new Viburnum have darker pink-colored flower buds than plants of `Gwenllian`. 3. Plants of the new Viburnum are more freely flowering than plants of `Gwenllian`.

BRIEFDESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet is a side perspective view of a typical plant of `Lisarose` grown in a container.

The photograph on the second sheet is a close-up view of a typical inflorescence of `Lisarose`.

The photograph on the third sheet is a close-up view of a typical leaf of `Lisarose`.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants of the new Viburnum grown during the early spring in five-liter containers in an outdoor nursery in Boskoop, The Netherlands and under conditionswhich closely approximate commercial Viburnum production. During the production of the plants, day temperatures ranged from 7.degree. C. to 15.degree. C. and night temperatures ranged from 2.degree. C. to 8.degree. C. Plants were four years old whenthe photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
