The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Mariposa Rose.
The new Petunia is a product of a planned breeding program conducted by the Inventor in Emerald, Victoria, Australia. The new Petunia originated from a cross made by the Inventor of a proprietary selection of Petunia×hybrida identified as code number 131098 as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number 429 as the male, or pollen, parent. The new Petunia was selected in October, 1993 on the basis of its attractive flower color.
Plants of the new Petunia are more compact, more low spreading, and differ in flower color compared to plants of the female parent selection. Compared to plants of the male parent selection, plants of the new Petunia have larger flowers and also differ in flower color.
Asexual reproduction of the new cultivar by terminal cuttings taken at Emerald, Victoria, Australia, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.
Plants of the cultivar Mariposa Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Mariposa Rose`. These characteristics in combination distinguish `Mariposa Rose` as a new and distinct cultivar:
1. Initially upright then low spreading and cascading plant habit.
2. Freely and continuous branching.
3. High vigor.
4. Large leaves.
5. Relatively early flowering.
6. Large reddish purple-colored flowers.
Plants of the cultivar Mariposa Rose can be compared to plants of th cultivar Revolution Pinkvein, disclosed in U.S. Plant Pat. No. 9,341. However in side-by-side comparisons conducted by the Inventor in Emerald, Victoria, Austrailia, plants of the cultivar Mariposa Rose have larger flowers, larger leaves, and flower earlier than plants of the cultivar Revolution Pinkvein.
Plants of the cultivar Mariposa Rose can also be compared to plants of the cultivar Sunlace, disclosed in U.S. Plant Pat. No. 10,044. However in side-by-side comparisons conducted by the Inventor in Emerald, Victoria, Australia, plants of the cultivar Mariposa Rose and Sunlace differ in flower color.
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 slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Petunia.
The photograph at the top of the sheet comprises a side perspective view of typical flowering plants of `Mariposa Rose`.
The photograph at the bottom of the sheet is a close-up view of a typical opened flower, a typical opening flower bud, and upper and lower surfaces of typical leaves of `Mariposa Rose`.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Plants grown in 25-cm containers were used for the following description with three or four plants per container. Plants were grown under full sun field conditions which closely approximate commercial production conditions during the spring in Bonsall, Calif. Day temperatures ranged from 13 to 25°C and night temperatures of ranged from 7 to 18°C
