USPP20419P2 - Geranium plant named ‘Regcan’ - Google Patents

Abstract

A new and distinct cultivar of Regal Geranium plant named ‘Regcan’, characterized by its upright, somewhat outwardly spreading and mounded plant habit; vigorous growth habit; freely basal branching habit; early and freely flowering habit; light and dark purple bi-colored flowers; and no requirement for cooling treatment for flower development.

Description

Botanical designation: Pelargonium grandiflorum.

Cultivar denomination: ‘Regcan’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Regal Geranium, botanically known as Pelargonium grandiflorum, and hereinafter referred to by the name ‘Regcan’.

The new Regal Geranium is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to develop new Regal Geraniumsthat do not require a cooling treatment for flower development.

The new Regal Geranium originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2002 of two unnamed proprietary selections of Pelargonium grandiflorum, not patented. The new Regal Geranium was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Dresden, Germany during the spring of 2003.

Asexual reproduction of the new Regal Geranium by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since October, 2003, has shown that the unique features of this new Regal Geranium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Regal Geranium have not been observed under all possible 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 ‘Regcan’. These characteristics in combination distinguish ‘Regcan’ as a new and distinct cultivar of Regal Geranium:

• • 1. Upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely basal branching habit.
  • 4. Early and freely flowering habit.
  • 5. Light and dark red purple bi-colored flowers.
  • 6. Does not require cooling treatment for flower development.

Plants of the new Regal Geranium differ primarily from plants of the parent selections in flower coloration. In addition, plants of the new Regal Geranium are more uniform than plants of the parent selections.

Plants of the new Regal Geranium can be compared to plants of the Pelargonium grandiflorum ‘Regli’, disclosed in a U.S. Plant patent application Ser. No. 11/820,029. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Regal Geranium differed from plants of ‘Regli’ in the following characteristics:

• • 1. Plants of the new Regal Geranium were taller than plants of ‘Regli’.
  • 2. Plants of the new Regal Geranium had smaller leaves than plants of ‘Regli’.
  • 3. Plants of the new Regal Geranium not as freely flowering as plants of ‘Regli’.
  • 4. Plants of the new Regal Geranium and ‘Regli’ differed in flower color as plants of ‘Regli’ had pink and purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Regal Geranium, 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 Regal Geranium. The photograph comprises a side perspective view of a typical flowering plant of ‘Regcan’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in Dresden, Germany in a glass-covered greenhouse during the winter and spring and under conditions which closely approximate commercial Regal Geranium production. During the production of the plants, day temperatures averaged 18° C., night temperatures averaged 16° C. and light levels ranged from 15 kilolux to 60 kilolux. Plants were six months from planting when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
