Geranium plant named ‘Pacyellim’

A new and distinct cultivar of Zonal Geranium plant named ‘Pacyellim’, characterized by its compact, upright and uniformly rounded plant habit; freely branching habit; moderately vigorous growth habit; dark green-colored leaves; early and freely flowering habit; and semi-double yellow-colored flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zonal Geranium plant, botanically known asPelargonium×hortorum, and hereinafter referred to by the name ‘Pacyellim’.

The new Zonal 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 create new uniform Zonal Geranium plants with attractive leaf and flower coloration.

The new Zonal Geranium plant originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2006 of two unnamed proprietary selections ofPelargonium×hortorum, not patented. The new Zonal 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 environment in Dresden, Germany during the spring of 2007.

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

SUMMARY OF THE INVENTION

Plants of the new Zonal 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 ‘Pacyellim’. These characteristics in combination distinguish ‘Pacyellim’ as a new and distinct Zonal Geranium plant:1. Compact, upright and uniformly rounded plant habit.2. Freely branching habit.3. Moderately vigorous growth habit.4. Dark green-colored leaves.5. Early and freely flowering habit.6. Semi-double yellow-colored flowers.

Plants of the new Zonal Geranium differ primarily from plants of the parent selections in plant vigor and flower color.

Plants of the new Zonal Geranium can be compared to plants of thePelargonium×hortorum‘Pacyell’, disclosed in U.S. Plant Pat. No. 20,906. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Zonal Geranium differed from plants of ‘Pacyell’ in the following characteristics:1. Plants of the new Zonal Geranium were more vigorous than plants of ‘Pacyell’.2. Plants of the new Zonal Geranium were more freely branching than plants of ‘Pacyell’.3. Plants of the new Zonal Geranium had slightly darker yellow-colored flowers than plants of ‘Pacyell’.4. Plants of the new Zonal Geranium had shorter peduncles and pedicels than plants of ‘Pacyell’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the winter and spring in 13-cm containers in a glass-covered greenhouse in Dresden, Germany and under conditions which closely approximate commercial Zonal 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 100 kilolux. Plants were three months old when the photograph was taken, and plants were six months old when the 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.Botanical classification:Pelargonium×hortorum‘Pacyellim’.Parentage:Female, or seed, parent.—Unnamed proprietary selection ofPelargonium×hortorum, not patented.Male or pollen parent.—Unnamed proprietary selection ofPelargonium×hortorum, not patented.Propagation:Type.—By vegetative terminal cuttings.Time to initiate roots, summer.—About 18 days at temperatures of 20° C.Time to initiate roots, winter.—About 22 days at temperatures of 20° C.Time to produce a rooted young plant, summer.—About 30 days at temperatures of 20° C.Time to produce a rooted young plant, winter.—About 30 days at temperatures of 18° C.Root description.—Fine, fibrous; white in color.Rooting habit.—Freely branching; dense.Plant description:Plant/growth habit.—Compact, upright and uniformly rounded plant habit; densely foliated; moderately vigorous growth habit; freely basal branching habit with about 20 lateral branches developing per plant.Plant height, to top of umbels.—About 30 cm.Plant height, to top of leaves.—About 20 cm.Plant width.—About 30 cm.Lateral branches.—Length: About 7 cm.
