Botanical designation: Petunia×hybrida.
Cultivar denomination: ‘Blue Frill Pink’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Blue Frill Pink’.
The new Petunia is a product of a planned breeding program conducted by the Inventor in Shizuocka Prefecture, Japan. The objective of the breeding program is to create new Petunia cultivars with attractive foliage shape and coloration.
The new Petunia originated from a cross-pollination made by the Inventor in April, 1999 in Shizuocka Prefecture, Japan of the Petunia×hybrida cultivar Bluette Purple, not patented, as the female, or seed, parent with an unidentified proprietary selection of Petunia×hybrida, not patented, as the male, or pollen, parent. The new Petunia 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 Shizuoka Prefecture, Japan in July, 2000.
Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Shizuoka Prefecture, Japan since July, 2000, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Blue Frill Pink has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Blue Frill Pink’. These characteristics in combination distinguish ‘Blue Frill Pink’ as a new and distinct cultivar of Petunia:
- 1. Outwardly spreading growth habit.
- 2. Freely branching and flowering plant habit.
- 3. Rapid growth rate.
- 4. Relatively small bright pink-colored flowers with distinct frilled edges.
Plants of the new Petunia can be compared to plants of the female parent, the cultivar Bluette Purple. Plants of the new Petunia differ from plants of the cultivar Bluette Purple in the following characteristics:
- 1. Plants of the new Petunia are more upright and have thinner stems than plants of the cultivar Bluette Purple.
- 2. Plants of the new Petunia have paler green-colored and thinner leaves than plants of the cultivar Bluette Purple.
- 3. Plants of the new Petunia are more fragrant than plants of the cultivar Bluette Purple.
Plants of the new Petunia can be compared to plants of the male parent, the unidentified selection of Petunia×hybrida. Plants of the new Petunia differ primarily from plants of the male parent selection in the following characteristics:
- 1. Plants of the new Petunia are more freely branching and more uniform than plants of the male parent selection.
- 2. Plants of the new Petunia has more intense pink-colored flowers than plants of the male parent selection.
Plants of the new Petunia can also be compared to plants of the cultivar Bluette White, disclosed in U.S. Plant Pat. No. 15,492. In side-by-side comparisons conducted in Shizuoka Prefecture, Japan, plants of the new Petunia and the cultivar Bluette White differed primarily in flower color as plants of the cultivar Bluette White had white-colored flowers.

DETAILED BOTANICAL DESCRIPTION
The photographs and following observations, measurements and values describe plants grown in Lompoc, Calif., under commercial practice during the winter and spring in a polycarbonate-covered greenhouse with day temperatures ranging from 21° C. to 24° C., night temperatures ranging from 16° C. to 18° C., and light levels ranging from about 5,000 to 9,000 foot candles. Plants were grown for about eleven weeks with one plant per 10-cm container. 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.
