USPP34111P2 - Solenostemon plant named ‘G18152’ - Google Patents

Abstract

A new and distinct cultivar of Solenostemon plant named ‘G18152’, characterized by its compact, upright to slightly outwardly spreading plant habit; moderately vigorous growth habit; freely branching habit; dense appearance; very dark purple-colored stems and leaves; and good garden performance.

Description

Botanical designation: Solenostemon scutellarioides.

Cultivar denomination: ‘G18152’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Solenostemon plant, botanically known as Solenostemon scutellarioides, commonly referred to as Coleus, and hereinafter referred to by the name ‘G18152’.

The new Solenostemon plant originated from a cross-pollination in September, 2017 in Bellefonte, Pa. of an unidentified proprietary selection of Solenostemon scutellarioides, not patented, as the female, or seed, parent, with a mixture of dark-leafed unidentified proprietary selections of Solenostemon scutellarioides, not patented, as the male, or pollen, parent. The new Solenostemon plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bellefonte, Pa. in August, 2018.

Asexual reproduction of the new Solenostemon plant by vegetative terminal cuttings in a controlled greenhouse environment in Bellefonte, Pa. since August, 2018 has shown that the unique features of this new Solenostemon plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Solenostemon plant has not been observed under all possible combinations of cultural practices and 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 ‘G18152’. These characteristics in combination distinguish ‘G18152’ as a new and distinct Solenostemon plant:

• • 1. Compact, upright to slightly outwardly spreading plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit; dense appearance.
  • 4. Very dark purple-colored stems and leaves.
  • 5. Good garden performance.

Plants of the new Solenostemon differ primarily from plants of the female parent selection in plant habit as plants of the new Solenostemon are more compact and uniform than plants of the female parent selection.

Plants of the new Solenostemon can be compared to plants of Solenostemon scutellarioides ‘ColorBlaze Dark Star’, not patented. In side-by-side comparisons plants of the new Solenostemon differ from plants of ‘ColorBlaze Dark Star’ in the following characteristics:

• • 1. Plants of the new Solenostemon are more compact than plants of ‘ColorBlaze Dark Star’.
  • 2. Plants of the new Solenostemon are more freely branching and are denser than plants of ‘ColorBlaze Dark Star’.

Plants of the new Solenostemon can be compared to plants of Solenostemon scutellarioides ‘Giant Exhibition Palisandra’, not patented. In side-by-side comparisons plants of the new Solenostemon differ from plants of ‘Giant Exhibition Palisandra’ in the following characteristics:

• • 1. Plants of the new Solenostemon are more compact than plants of ‘Giant Exhibition Palisandra’.
  • 2. Plants of the new Solenostemon are more freely branching and are denser than plants of ‘Giant Exhibition Palisandra’.
  • 3. Plants of the new Solenostemon have smaller leaves than plants of ‘Giant Exhibition Palisandra’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Solenostemon 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 Solenostemon.

The photograph is a side perspective view of a typical plant of ‘G18152’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the autumn and winter in 10.8-cm containers in a glass-covered greenhouse in Loudon, N.H. and under cultural practices typical of commercial Solenostemon production. During the production of the plants, average daily temperatures were 18° C. Plants were grown under long day/short night conditions and were pinched two weeks after planting. Plants were ten weeks from planting when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used. Measurements were taken on individual plants.
