Abstract
A new and distinct cultivar of Pentas plant named ‘DPRP2’, characterized by its compact, upright and mounded growth habit; freely branching habit; freely flowering habit; double red purple-colored flowers that are held above the foliage on strong peduncles; and good garden performance.
Description
Botanical designation: Pentas lanceolata.
Cultivar denomination: ‘DPRP2’.
-
- Title: Pentas Plant Named ‘DPVG’Applicant: Tanaka Nobuyuki Ser. No.: U.S. Plant patent application No. 11/978,514.
The present invention relates to a new and distinct cultivar of Pentas, botanically known as Pentas lanceolata and hereinafter referred to by the name ‘DPRP2’.
The new Pentas is a product of a planned breeding program conducted by the Inventor in Aichi, Japan. The objective of the breeding program is to create new compact Pentas cultivars with double flowers.
The new Pentas originated from a cross-pollination made by the Inventor in March, 2002 in Aichi, Japan of a proprietary selection of Pentas lanceolata identified as code name D. W. Red, not patented, as the female, or seed, parent with an unnamed proprietary selection of Pentas lanceolata, not patented, as the male, or pollen, parent. The new Pentas was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Aichi, Japan in March, 2003.
Asexual reproduction of the new Pentas by cuttings in a controlled environment in Aichi, Japan since April, 2003, has shown that the unique features of this new Pentas are stable and reproduced true to type in successive generations.
The cultivar DPRP2 has 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, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DPRP2’. These characteristics in combination distinguish ‘DPRP2’ as a new and distinct cultivar of Pentas:
-
- 1. Compact, upright and mounded growth habit.
- 2. Freely branching habit.
- 3. Freely flowering habit.
- 4. Double red purple-colored flowers that are held above the foliage on strong peduncles.
- 5. Good garden performance.
Plants of the new Pentas can be compared to plants of the parent selections. Plants of the new Pentas differ from plants of the parent selections primarily in flower form and color.
Plants of the new Pentas can also be compared to plants of the cultivar DPVG, disclosed in U.S. Plant patent application Ser. No. 11/978,514. Plants of the new Pentas differ primarily from plants of the cultivar DPVG in flower color as plants of the cultivar DPVG have purple-colored flowers.
Plants of the new Pentas can also be compared to plants of the Pentas cultivar New Look Violet, not patented. In side-by-side comparisons conducted in Bonsall, Calif. plants of the new Pentas differed from plants of the cultivar New Look Violet in the following characteristics:
-
- 1. Plants of the new Pentas were more compact than plants of the cultivar New Look Violet.
- 2. Plants of the new Pentas had double flowers whereas plants of the cultivar New Look Violet had single flowers.
The accompanying colored photographs illustrate the overall appearance of the new Pentas, 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 accurately describe the colors of the new Pentas.
The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘DPRP2’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical flowers of ‘DPRP2’.
The photograph and following observations, measurements and values describe plants grown in Bonsall, Calif. during the spring in a polyethylene-covered greenhouse and conditions which approximate commercial Pentas production. During the production of the plants, day temperatures ranging from 13° C. to 38° C. and night temperatures ranging from 13° C. to 21° C. Rooted young plants had been growing for about nine weeks when the photographs 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.
