Geranium plant named ‘Balcolbugi’

Abstract

A new and distinct cutlivar of Geranium plant named ‘Balcolbugi’, characterized by its burgandy-colored double flowers; cascading and mounded growth habit; freely basal branching habit; and medium green leaves with darker green zonation pattern.

Description

BACKGROUND OF THE INVENTION

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

The new Geranium is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program was to develop new cultivars with freely-branching and vigorous growth habit, medium or dark green-colored foliage, uniform flowering, and interesting flower and foliage colors.

The new Geranium originated from a self-pollination made by the Inventor of the proprietary Pelargonium peltatum selection 8176-12. The cultivar ‘Balcolbugi’ was discovered and selected by the Inventor as a flowering plant within the progreny of the self-pollination in a controlled environment in Arroyo Grande, Calif., in 1998.

Asexual reproduction of the new cultivar by terminal cuttings taken at Arroyo Grande, Calif., 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 ‘Balcolbugi’. These characteristics in combination distinguish ‘Balcolbugi’ as a new and distinct cultivar:

1. Cascading and mounded growth habit.

2. Freely basal branching habit.

3. Medium green leaves with darker green zonation pattern.

4. Burgundy-colored double flowers.

Plants of the new Geranium differ primarily from plants of the parent selection in flower form as flowers of the parent selection are semi-double and flowers of the new Geranium are double.

The new Geranium can be compared to the cultivar, ‘Butterfly’, not patented. However, in side-by-side comparisons conducted in Arroyo Grande, Calif., plants of the new Geranium differ from plants of the cultivar ‘Butterfly’ in the following characteristics:

1. Plants of the new Geranium are much more freely branching than plants of the cultivar ‘Butterfly’.

2. Plants of the new Geranium have longer lateral branches but shorter internodes and more leaves per lateral branch than plants of the cultivar ‘Butterfly’.

3. Plants of the new Geranium have smaller leaves than plants of the cultivar ‘Butterfly’.

4. Plants of the new Geranium have smaller flowers than plants of the cultivar ‘Butterfly’.

5. Plants of the new Geranium have fewer flowers per umbel than plants of the cultivar ‘Butterfly’.

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 iin colored reproductions of this type. The photograph comprises a side perspective view of a typical flowering plant of ‘Balcolbugi’. 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 Geranium.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Balcolbugi’ has 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 following observations, measurements and comparisons describe plants grown 10-cm pots in Arroyo Grande, Calif., under commercial practice in a polycarbonate-covered greenhouse with day temperatures about 20 to 22° C., night temperatures about 18 to 20° C. and light levels about 2,500 to 3,000 foot-candles. Plants used for the photograph and description were about 8 to 10 weeks from planting rooted cuttings. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
