Geranium plant named ‘Pacham’

Abstract

A new and distinct cultivar of Ivy Geranium plant named ‘Pacham’, characterized by its upright, outwardly spreading and trailing plant habit; vigorous growth habit; freely basal branching habit; large single and light purple-colored flowers; and good garden performance.

Description

Botanical designation: Pelargonium peltatum.

Cultivar denomination: ‘Pacham’.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following application: Geranium Plant Named ‘Pacharl’ (U.S. Plant patent application Ser. No. 11/073,468); Andrea Michalik, applicant.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ivy Geranium plant, botanically known as Pelargonium peltatum, and hereinafter referred to by the name ‘Pacham’.

The new Ivy Geranium is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program was to develop new large Ivy Geraniums with attractive flower coloration.

The new Ivy Geranium originated from a cross-pollination made by the Inventor during 2001 of two proprietary selections of Pelargonium peltatum, not patented. The cultivar Pacham was discovered and selected by the Inventor as a flowering plant within the progeny from the stated cross-pollination in a controlled environment in Dresden, Germany in 2002.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Dresden, Germany since 2002 has shown that the unique features of this new Ivy 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 ‘Pacham’. These characteristics in combination distinguish ‘Pacham’ as a new cultivar and distinguish it from other known Ivy Geranium cultivars:

• • 1. Upright, outwardly spreading and trailing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely basal branching habit.
  • 4. Large, single and light purple-colored flowers.
  • 5. Good garden performance.

Plants of the new Ivy Geranium differ primarily from plants of the parent selections in flower coloration.

Plants of the new Ivy Geranium can be compared to plants of the cultivar Pacharl, disclosed in U.S. Plant patent application Ser. No. 11/073,468. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Ivy Geranium differed from plants of the cultivar Pacharl in the following characteristics:

• • 1. Plants of the new Ivy Geranium were smaller and had shorter internodes than plants of the cultivar Pacharl.
  • 2. Plants of the new Ivy Geranium had smaller leaves than plants of the cultivar Pacharl.
  • 3. Plants of the new Ivy Geranium had smaller umbels than and were not as freely flowering as plants of the cultivar Pacharl.
  • 4. Flower color of plants of the new Ivy Geranium was light purple whereas flower color of plants of the cultivar Pacharl was scarlet red.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Flower and foliage 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 Ivy Geranium. The photograph comprises a side perspective view of a typical flowering plant of ‘Pacham’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Pacham 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 photograph, following observations and averaged measurements describe plants grown during the spring in containers in Dresden, Germany, and under commercial practice in a glass-covered greenhouse with day temperatures about 18° C., night temperatures about 16° C. and light levels less than 60,000 lux. Plants used for the photograph and the description were about four months old. 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.
