Abstract

A new and distinct cultivar of Geranium plant named ‘Amri Cherose Two’, characterized by its upright, outwardly spreading and mounded growth habit; freely basal branching habit; dark green-colored leaves; freely flowering habit with many large flower umbels per plant; and flower umbels with numerous red purple-colored single flowers.

Description

Botanical classification/cultivar designation: Pelargonium×hortorum cultivar Amri Cherose Two.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium×hortorum, commercially known as a Zonal Geranium, and hereinafter referred to by the name ‘Amri Cherose Two’.

The new Geranium is a product of a planned breeding program conducted by the Inventor in Gilroy, Calif. The objective of the breeding program is to develop new Zonal Geranium cultivars with good basal branching, freely flowering habit and attractive flower and foliage coloration.

The new Geranium originated from a cross-pollination made by the Inventor in February, 1997 of a proprietary Pelargonium×hortorum selection identified as code number 5746-1, not patented, as the female, or seed, parent with a proprietary Pelargonium×hortorum selection identified as code number 5252-1, not patented, as the male, or pollen, parent. The cultivar Amri Cherose Two was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Gilroy, Calif. in September, 1997.

Asexual reproduction of the new cultivar by terminal cuttings at Gilroy, Calif., since September, 1997 has shown that the unique features of this new Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

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

• • 1. Upright, outwardly spreading and mounded growth habit.
  • 2. Freely basal branching habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit with many flower umbels per plant.
  • 5. Large flower umbels with numerous red purple-colored single flowers.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Geranium had single flowers whereas plants of the female parent selection had semi-double flowers.
  • 2. Plants of the new Geranium and the female parent selection differed in flower color as plants of the female parent selection had bluish rose-colored flowers.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Geranium had darker-green colored leaves than plants of the male parent selection.
  • 2. Plants of the new Geranium and the male parent selection differed in flower color as plants of the male parent selection had bluish rose-colored flowers.

The new Geranium can be compared to the cultivar, Americana Cherry Rose, disclosed in U.S. Plant Pat. No. 7,937. However, in side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the cultivar Americana Cherry Rose in the following characteristics:

• • 1. Plants of the new Geranium were more vigorous than plants of the cultivar Americana Cherry Rose.
  • 2. Plants of the new Geranium were more freely branching than plants of the cultivar Americana Cherry Rose.
  • 3. Plants of the new Geranium had slightly larger leaves than plants of the cultivar Americana Cherry Rose.
  • 4. Leaf color of plants of the new Geranium was lighter green than leaf color of plants of the cultivar Americana Cherry Rose.

Flower and foliage colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Geranium.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Amri Cherose Two have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice in a fiberglass-covered greenhouse during the late spring with day temperatures about 27 to 29° C., night temperatures about 16 to 18° C. and light levels about 2,000 foot-candles. Plants used for the photographs and description were about eight to twelve weeks from planting rooted cuttings. 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.
