Abstract

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

Description

Botanical classification/cultivar designation: Pelargonium×hortorum cultivar Amri Derose 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 Derose 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 January, 1999 of a proprietary Pelargonium×hortorum selection identified as code number 7722-1, not patented, as the female, or seed, parent with a proprietary Pelargonium×hortorum selection identified as code number 7889-6, not patented, as the male, or pollen, parent. The cultivar Amri Derose 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 June, 1999.

Asexual reproduction of the new cultivar by terminal cuttings at Gilroy, Calif., since June, 1999 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 Derose Two’. These characteristics in combination distinguish ‘Amri Derose Two’ as a new and distinct Geranium cultivar:

• • 1. Upright, outwardly spreading and rounded growth habit.
  • 2. Freely basal branching habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit with many large flower umbels per plant.
  • 5. Flower umbels with numerous dark red purple-colored semi-double 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 were more vigorous than plants of the female parent selection.
  • 2. Plants of the new Geranium had darker green-colored leaves than plants of the female parent selection.
  • 3. Plants of the new Geranium and the female parent selection differed in flower color as plants of the female parent selection had red-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 were more compact than plants of the male parent selection.
  • 2. Plants of the new Geranium were more freely basal branching than plants of the male parent selection.
  • 3. Plants of the new Geranium had darker colored flowers than plants of the male parent selection.

The new Geranium can be compared to the cultivar, Americana Deep Rose, disclosed in U.S. Plant Pat. No. 9,383. However, in side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the cultivar Americana Deep Rose in the following characteristics:

• • 1. Plants of the new Geranium had larger flower umbels than plants of the cultivar Americana Deep Rose.
  • 2. Plants of the new Geranium had longer peduncles than plants of the cultivar Americana Deep Rose.
  • 3. Plants of the new Geranium had darker colored flowers than plants of the cultivar Americana Deep Rose.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Amri Derose 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 six months from planting rooted cuttings.
