plant named ‘KL1117mut1’

Abstract

A new and distinct cultivar of Petunia plant named ‘KL1117mut1’, characterized by its outwardly spreading, mounding to trailing plant habit; freely branching and moderately vigorous growth habit; early and freely flowering habit; single flowers that are violet in color; and good garden performance.

Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘KL1117mut1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia X hybrida and hereinafter referred to by the name ‘KL1117mut1’.

The new Petunia plant is a naturally-occurring whole plant mutation of Petunia X hybrida ‘KL 1117’, disclosed in U.S. Plant Pat. No. 25,485. The new Petunia was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘KL 1117’ in a controlled greenhouse environment in Alajuela, Costa Rica on Sep. 10, 2015. Asexual reproduction of the new Petunia plant by vegetative tip cuttings in a controlled greenhouse environment in Alajuela, Costa Rica since Sep. 10, 2015, has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘KL1117mut1’. These characteristics in combination distinguish ‘KL1117mut1’ as a new and distinct Petunia plant:

• • 1. Outwardly spreading, mounding to trailing plant habit.
  • 2. Freely branching and moderately vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Single flowers that are violet in color.
  • 5. Good garden performance.

Plants of the new Petunia differ primarily from plants of the mutation parent, ‘KL 1117’, in flower color as plants of ‘KL 1117’ have white-colored flowers. In addition, leaves of plants of the new Petunia are darker green in color than leaves of plants of ‘KL1117’.

Plants of the new Petunia can be compared to plants of ‘Sunsurf Skytatsu’, disclosed in U.S. Plant Pat. No. 25,163. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Sunsurf Skytatsu’ in the following characteristics:

• • 1. Plants of the new Petunia are more uniform than plants of ‘Sunsurf Skytatsu’.
  • 2. Leaves of plants of the new Petunia are darker green in color than leaves of plants of ‘Sunsurf Skytatsu’.
  • 3. Plants of the new Petunia are more freely flowering than plants of ‘Sunsurf Skytatsu’.
  • 4. Flowers of plants of the new Petunia are flatter than flowers of plants of ‘Sunsurf Skytatsu’.

Plants of the new Petunia can also be compared to plants of ‘KEIlavbu’, disclosed in U.S. Plant Pat. No. 13,542. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘KEIlavbu’ in the following characteristics:

• • 1. Plants of the new Petunia are more freely flowering than plants of ‘KEIlavbu’.
  • 2. Flowers of plants of the new Petunia are flatter than flowers of plants of ‘KEIlavbu’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 10-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial Petunia production.
