Abstract: A new and distinct cultivar of Malcolmia plant named `Sunmalpin`, characterized by its upright and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; uniform and long flowering period; light pink-colored flowers; and good garden performance.
Claim: It is claimed:

1. A new and distinct Malcolmia plant named `Sunmalpin` as illustrated and described.
Description: Cultivar denomination: Malcolmiamaritima.

Cultivar denomination: `SUNMALPIN`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Malcolmia plant, botanically known as Malcolmia maritima and hereinafter referred to by the name `Sunmalpin`.

The new Malcolmia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new upright and mounding Malcolmia plants with long flowering time,winter hardiness, and attractive and uniform flower coloration.

The new Malcolmia plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in March, 2004 of a proprietary selection of Malcolmia maritima identified as code number 3AK-18a, not patented, as the female, orseed, parent with a proprietary selection of Malcolmia maritima identified as code number 3AK-20, not patented, as the male, or pollen, parent. The new Malcolmia plant was discovered and selected by the Inventor as a single flowering plant from withinthe progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in December, 2004.

Asexual reproduction of the new Malcolmia plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since January, 2005, has shown that the unique features of this new Malcolmia plant are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Malcolmia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Sunmalpin`. These characteristics in combination distinguish `Sunmalpin` as a new and distinct cultivar of Malcolmia: 1. Upright andmounding plant habit. 2. Vigorous growth habit. 3. Freely branching and flowering plant habit. 4. Uniform and long flowering period. 5. Light pink-colored flowers. 6. Good garden performance.

Plants of the new Malcolmia can be compared to plants of the female parent selection. Plants of the new Malcolmia differ primarily from plants of the female parent selection in the following characteristics: 1. Plants of the new Malcolmia aremore freely branching than plants of the female parent selection. 2. Plants of the new Malcolmia have larger flowers than plants of the female parent selection.

Plants of the new Malcolmia can be compared to plants of the male parent selection. Plants of the new Malcolmia differ primarily from plants of the male parent selection in plant form as plants of the new Malcolmia have shorter internodes andare denser than plants of the male parent selection.

Plants of the new Malcolmia can also be compared to plants of Malcolmia maritima `Virginian Stock`, not patented. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Malcolmia and `Virginian Stock` differedprimarily in the following characteristics: 1. Plants of the new Malcolmia were more freely branching and denser than plants of `Virginian Stock`. 2. Plants of the new Malcolmia had shorter lateral branches than plants of `Virginian Stock`. 3. Plants of the new Malcolmia had shorter leaves and petioles than plants of `Virginian Stock`. 4. Plants of the new Malcolmia were more freely flowering than plants of `Virginian Stock`. 5. Plants of the new Malcolmia and `Virginian Stock` differed inflower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Malcolmia 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 Malcolmia plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Sunmalpin` grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers of `Sunmalpin`.
