Abstract: A new and distinct cultivar of Papaver plant named `Pink Pearl`, characterized by its upright and compact plant habit; moderately vigorous growth habit; freely flowering habit; single flowers with light red-colored petals; and strong peduncles.
Claim: It is claimed:

1. A new and distinct cultivar of Papaver plant named `Pink Pearl`, as illustrated and described.
Description: Botanicaldesignation: Papaver orientale.

Cultivar denomination: `Pink Pearl`.


The present Invention relates to a new and distinct cultivar of Papaver plant, botanically known as Papaver orientale, commercially referred to as Oriental Poppy, and hereinafter referred to by the cultivar name Pink Pearl.

The new Papaver is a product of a planned breeding program conducted by the Inventor in Rijpwetering, The Netherlands. The objective of the breeding program is to develop new Papaver cultivars with compact plant habit and numerous flowers.

The new Papaver originated from a cross-pollination made by the Inventor in 2000 of two unnamed selections of Papaver orientale, not patented. The new Papaver was discovered and selected as a single plant by the Inventor in 2004 in a controlledenvironment in Rijpwetering, The Netherlands, from the resultant progeny of the stated cross-pollination.

Asexual reproduction of the new cultivar by cuttings at Rijpwetering, The Netherlands since 2004, has shown that the unique features of this new Papaver are stable and reproduced true to type in successive generations.


Plants of the cultivar Pink Pearl 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 ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Pink Pearl`. These characteristics in combination distinguish `Pink Pearl` as a new and distinct Papaver cultivar: 1. Upright and compactplant habit. 2. Moderately vigorous growth habit. 3. Freely flowering habit. 4. Single flowers with light red-colored petals. 5. Strong peduncles.

Plants of the cultivar Pink Pearl differ from plants of the parent selections primarily in plant height as plants of the new Papaver are more compact than plants of the parent selections.

Plants of the new Papaver can also be compared to plants of the Papaver cultivar Elizabeth, not patented. In side-by-side comparisons conducted in Rijpwetering, The Netherlands, plants of the new Papaver differed from plants of the cultivarElizabeth in the following characteristics: 1. Plants of the new Papaver were more compact than plants of the cultivar Elizabeth. 2. Plants of the new Papaver had darker colored flowers than plants of the cultivar Elizabeth. 3. Plants of the newPapaver had stronger peduncles than plants of the cultivar Elizabeth.


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

The photograph at the top of the sheet comprises a side perspective view of typical plants grown in an outdoor nursery.

The photograph in the center of the sheet is a close up view of a typical flower of `Pink Pearl`.

The photograph at the bottom of the sheet is a close-up view of a typical leaf of `Pink Pearl`.


In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the abovementioned photographs andfollowing observations and measurements were grown in an outdoor nursery in Lisserbroek, The Netherlands, and under conditions which closely approximate commercial production conditions during the spring. The photographs, measurements and observationswere taken in may when the plants were about two years old. During this time, day temperatures ranged from C. to C. and night temperatures ranged from C. to C. Botanical classification: Papaver orientalecultivar Pink Pearl.
