plant named ‘G14158’

Abstract

A new and distinct cultivar of Hypoestes plant named ‘G14158’, characterized by its upright and mounding plant habit; moderately vigorous growth habit; freely branching habit; large dark green and red purple bi-colored leaves; and relative tolerance to high light conditions.

Description

Botanical designation: Hypoestes phyllostachya.

Cultivar denomination: ‘G14158’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypoestes plant, botanically known as Hypoestes phyllostachya and hereinafter referred to by the name ‘G14158’.

The new Hypoestes plant is a product of a planned breeding program conducted by the Inventors in Bellefonte, Pa. The objective of the breeding program is to create new vigorous Hypoestes plants with attractive leaves and high light tolerance.

The new Hypoestes plant is a naturally-occurring branch mutation of an unnamed proprietary selection of Hypoestes phyllostachya, not patented. The new Hypoestes plant was discovered and selected by the Inventors on a single plant within a population of plants of the mutation selection in a controlled greenhouse environment in Bellefonte, Pa. on Aug. 15, 2014.

Asexual reproduction of the new Hypoestes plant by terminal cuttings in a controlled greenhouse environment in Bellefonte, Pa. since Aug. 15, 2014 has shown that the unique features of this new Hypoestes plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Hypoestes 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 ‘G14158’. These characteristics in combination distinguish ‘G14158’ as a new and distinct Hypoestes plant:

• • 1. Upright and mounding plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Large dark green and red purple bi-colored leaves.
  • 5. Relatively tolerant to high light conditions.

Compared to plants of the mutation parent selection, plants of the new Hypoestes differ primarily in the following characteristics:

• • 1. Plants of the new Hypoestes are more vigorous than and not as compact as plants of the mutation parent selection.
  • 2. Plants of the new Hypoestes have thicker leaves than plants of the mutation parent selection.
  • 3. Plants of the new Hypoestes are more tolerant to high light conditions than plants of the mutation parent selection.

Compared to plants of Hypoestes phyllostachya ‘G14160’, disclosed in U.S. Plant Pat. No. 29,842, plants of the new Hypoestes differ primarily in the following characteristics:

• • 1. Plants of the new Hypoestes are not as vigorous as plants of ‘G14160’.
  • 2. Plants of the new Hypoestes are more freely branching than plants of ‘G14160’.
  • 3. Plants of the new Hypoestes and ‘G14160’ differ in leaf color as plants of the new Hypoestes have brighter red purple-colored splotches than plants of ‘G14160’.

Plants of the new Hypoestes can also be compared to plants of Hypoestes phyllostachya ‘Splash Select Red’, not patented. In side-by-side comparisons, plants of the new Hypoestes differ primarily from plants of ‘Splash Select Red’ in the following characteristics:

• • 1. Plants of the new Hypoestes are more vigorous than and not as compact as plants of ‘Splash Select Red’.
  • 2. Plants of the new Hypoestes have thicker leaves than plants of ‘Splash Select Red’.
  • 3. Plants of the new Hypoestes are more tolerant to high light conditions than plants of ‘Splash Select Red’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Hypoestes plant 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 Hypoestes plant.

The photograph (FIG. 1) is a side perspective view of a typical plant of ‘G14158’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the late winter in 10.8-cm containers in a corrugated polycarbonate-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial potted Hypoestes production. During the production of the plants, day temperatures averaged 20° C., night temperatures averaged 18° C. and light levels averaged 6,790 foot-candles. Plants were pinched one time and were nine weeks old 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.
