Abstract: A new and distinct cultivar of Vinca plant named `24 Carat`, characterized by its compact, outwardly spreading to trailing plant habit; short internodes; densely foliated habit; strong and healthy leaves; developing leaves that are yellow in color becoming green with development; and good garden performance.
Claim: It is claimed:

1. A new and distinct Vinca plant named `24 Carat` as illustrated and described.
Description: Botanical designation: Vinca minor.

Cultivar denomination: `24 Carat`.


The present invention relates to a new and distinct cultivar of Vinca, botanically known as Vinca minor and hereinafter referred to by the name `24 Carat`.

The new Vinca is a naturally-occurring branch mutation of an unnamed selection of Vinca minor, not patented. The new Vinca was discovered and selected by the Inventor from within a population of plants of the parent selection in a controlledgreenhouse environment in Dahlonega, Ga. in June, 2002.

Asexual reproduction of the new Vinca by vegetative cuttings in a controlled greenhouse environment in Dahlonega, Ga. since July, 2002, has shown that the unique features of this new Vinca are stable and reproduced true to type in successivegenerations.


Plants of the new Vinca 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 `24 Carat`. These characteristics in combination distinguish `24 Carat` as a new and distinct cultivar of Vinca: 1. Compact, outwardlyspreading to trailing plant habit. 2. Short internodes; densely foliated. 3. Strong and healthy leaves. 4. Developing leaves yellow in color becoming green with development. 5. Good garden performance.

Plants of the new Vinca differ primarily from plants of the parent selection in the following characteristics: 1. Plants of the new Vinca are not as vigorous as plants of the parent selection. 2. Developing leaves of plants of the new Vincaare yellow in color whereas developing leaves of plants of the parent selection are green in color.

Plants of the new Vinca can be compared to plants of Vinca minor `Sunny Skies`, disclosed in U.S. Plant Pat. No. 13,466. Plants of the new Vinca and `Sunny Skies` differ in the following characteristics: 1. Plants of the new Vinca are not asupright as plants of `Sunny Skies`. 2. Plants of the new Vinca and `Sunny Skies` differ in leaf color as plants of `Sunny Skies` have golden yellow green and dark green-variegated leaves.


The accompanying colored photograph illustrates the overall appearance of the new Vinca, 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 fromthe color values cited in the detailed botanical description which accurately describe the colors of the new Vinca. The photograph comprises a top perspective view of a typical plant of `24 Carat` grown in an outdoor nursery.


The aforementioned photograph and following observations, measurements and values describe plants grown during the spring and summer in an outdoor nursery in Tolar, Tex. Plants had been growing for a year in the outdoor nursery when thephotograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Botanicalclassification: Vinca minor `24 Carat`. Parentage: Naturally-occurring branch mutation of an unnamed selection of Vinca minor, not patented. Propagation: Type.--By vegetative cuttings.

Fully expandedleaves, upper surface: Close to 137A; venation, close to 137A. Fully expanded leaves, lower surface: Close to 147B; venation, close to 147B. Petiole: Length: About 5 mm. Diameter: About 1 mm. Texture, upper and lower surfaces: Smooth, glabrous. Color, developing leaves, upper and lower surfaces: Close to 148C, flushed with close to 187B. Color, fully expanded leaves, upper and lower surfaces: Close to 148C. Flower description: Flower development as not been observed on plants of the newVinca. Disease/pest resistance: Plants of the new Vinca have not been observed to be resistant to pathogens and pests common to Vinca. Garden performance: Plants of the new Vinca have been observed to have good garden performance and tolerate rain,wind and temperatures ranging from about C. to about C.
