Abstract

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

Description

Botanical designation: (Pelargonium×hortorum)×P. tongaense.

Variety denomination: ‘Cante Ros’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as (Pelargonium×hortorum)×P. tongaense, commercially known as an interspecific Geranium, and hereinafter referred to by the name ‘Cante Ros’.

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 Geranium cultivars with mounded plant habit, good basal branching, large flowers, attractive flower and foliage coloration and resistance to leaf oedema.

The new Geranium originated from a cross-pollination made by the Inventor in January, 2000 of a proprietary (Pelargonium×hortorum)×P. tongaense selection identified as code number 8301-2, not patented, as the female, or seed, parent with a proprietary (Pelargonium×hortorum)×P. tongaense selection identified as code number 7367-4, not patented, as the male, or pollen, parent. The cultivar Cante Ros was discovered and selected by the Inventor as a single flowering plant within the progeny from this cross-pollination in a controlled environment in Gilroy, Calif. in June, 2000.

Asexual reproduction of the new cultivar by terminal cuttings taken at Gilroy, Calif., since June, 2000 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 ‘Cante Ros’. These characteristics in combination distinguish ‘Cante Ros’ 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. Flower umbels with numerous red purple-colored single flowers.
  • 6. Resistant to leaf oedema.

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 lighter green-colored leaves than plants of the female parent selection.
  • 2. Plants of the new Geranium and the female parent selection differed in flower color as plants of the female parent selection had rose scarlet-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 larger 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 coral pink-colored flowers.

The new Geranium can be compared to the cultivar, Balgalpipn, (U.S. Plant Pat. No. 11,925). However, in side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the cultivar Balgalpipn in the following characteristics:

• • 1. Plants of the new Geranium did not have a distinct leaf zonation pattern whereas plants of the cultivar Balgalpipn had a distinct leaf zonation pattern.
  • 2. Plants of the new Geranium had single flowers whereas plants of the cultivar Balgalpipn had semi-double flowers.
  • 3. Plants of the new Geranium and the cultivar Balgalpipn differed in flower color as plants of the cultivar Balgalpipn were coral pink in color.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Cante Ros 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 polyethylene-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 five months 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.
