Abstract

A new and distinct cultivar of Lemon-scented Geranium plant named ‘Pacperfu’, characterized by its upright and uniformly rounded plant habit; moderately vigorous growth habit; freely basal branching habit; leaves that are strongly lemon-scented; early and freely flowering habit; and dark red purple and light purple-colored flowers.

Description

Botanical designation: Pelargonium crispum.

Cultivar denomination: ‘Pacperfu’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lemon-scented Geranium plant, botanically known as Pelargonium crispum, and hereinafter referred to by the name ‘Pacperfu’.

The new Lemon-scented Geranium plant 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 freely flowering Lemon-scented Geranium plants with strongly fragrant leaves.

The new Lemon-scented Geranium plant originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2007 of two unnamed proprietary selections of Pelargonium crispum, not patented. The new Lemon-scented Geranium plant 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 2008.

Asexual reproduction of the new Lemon-scented Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since October, 2008 has shown that the unique features of this new Lemon-scented Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lemon-scented Geranium have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘Pacperfu’. These characteristics in combination distinguish ‘Pacperfu’ as a new and distinct Lemon-scented Geranium plant:

- 1. Upright and uniformly rounded plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely basal branching habit.
- 4. Leaves that are strongly lemon-scented.
- 5. Early and freely flowering habit.
- 6. Dark red purple and light purple-colored flowers.
- 7. Does not require cooling treatment for flower development.

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

Plants of the new Lemon-scented Geranium can be compared to plants of the Pelargonium crispum ‘Pacburg’, disclosed in U.S. Plant Pat. No. 14,862. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Lemon-scented Geranium differed from plants of ‘Pacburg’ in the following characteristics:

- 1. Plants of the new Lemon-scented Geranium had thicker lateral branches than plants of ‘Pacburg’.
- 2. Plants of the new Lemon-scented Geranium had broader leaves than plants of ‘Pacburg’.
- 3. Leaves of plants of the new Lemon-scented Geranium were strongly fragrant whereas leaves of plants of ‘Pacburg’ were not fragrant.
- 4. Plants of the new Lemon-scented Geranium and ‘Pacburg’ differed slightly in flower color.
- 5. Plants of the new Lemon-scented Geranium had shorter pedicels than plants of ‘Pacburg’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Lemon-scented Geranium plant 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 Lemon-scented Geranium plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Pacperfu’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 13-cm containers during the winter, spring and summer in a glass-covered greenhouse in Dresden, Germany and under cultural practices which closely approximate commercial Lemon-scented Geranium production. During the production of the plants, day temperatures averaged 16° C., night temperatures averaged 14° C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were pinched six weeks after planting and were four months old when the photograph was taken and nine months old when the detailed description was 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.
