Petunia plant named ‘Petnitbl’

Abstract

A new and distinct cultivar of Petunia plant named ‘Petnitbl’ characterized by its trailing, outwardly spreading and mounded plant habit, freely branching habit, freely flowering habit, single flowers that are very dark blue in color, and good garden performance.

Description

Latin name of the genus and species of the plant claimed: Petunia hybrida.

Varietal denomination: ‘Petnitbl’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Petunia plant botanically known as Petunia hybrida and referred to by the cultivar name ‘Petnitbl.’

The new Petunia is the product of a planned breeding program conducted by the inventor in Enkhuizen, Netherlands. The new Petunia cultivar is freely flowering with trailing and spreading plant habit and attractive leaf and flower coloration.

The new Petunia originated from a cross-pollination made by the inventor in August 2000 of a proprietary selection of Petunia hybrida identified as code number ‘Y1003’ not patented, as the female, or seed parent, with a proprietary selection of Petunia hybrida identified as code number ‘Z4120,’ not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny of the cross-pollination in a controlled environment in Enkhuizen, Netherlands in June 2001.

Asexual reproduction of the new cultivar by terminal vegetative cuttings since June 2001, in Enkhuizen, Netherlands has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Petnitbl’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Petnitbl.’ These characteristics in combination distinguish ‘Petnitbl’ as a new and distinct cultivar:

• • 1. Trailing, outwardly spreading and mounded plant habit
  • 2. Freely branching habit
  • 3. Freely flowering habit
  • 4. Single flowers that are very dark velvet like blue in color
  • 5. Good garden performance

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plants of the new Petunia named ‘Petnitbl’ differed from plants of the female parent selection in the following characteristic:

• • 1. Plants of the new Petunia are slightly mounded whereas plants of the female parent selection are very flat and trailing.

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plants of the new Petunia differed from plants of the male parent selection in the following characteristic:

• • 1. Plants of the new Petunia have medium size flowers whereas flowers of the male parent selection are very big.

DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates 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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia.

DESCRIPTION OF THE NEW CULTIVAR

The observations and measurements describe plants grown in Enkhuizen, The Netherlands, practice circumstances indoor in hanging baskets of diameter 25 cm during the early Spring with day temperatures ranging from 14 to 16° C., night temperatures ranging from 12 to 14° C. Plants used for the photographs and description were about 10 weeks from planting rooted cuttings.
