Claims
It is claimed:
1. A new and distinct Regal Geranium plant named `Regpurstr` as
illustrated and described.
Description
Botanical designation: Pelargonium grandiflorum.
Cultivar denomination: `REGPURSTR`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Regal Geranium plant, botanically known as Pelargonium
grandiflorum, and hereinafter referred to by the name
`Regpurstr`.
The new Regal 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 early flowering
Regal Geranium plants that do not require a cooling treatment for
flower development.
The new Regal Geranium plant originated from a cross-pollination
made by the Inventor in Dresden, Germany during the summer of 2011
of two unnamed proprietary selections of Pelargonium grandiflorum,
not patented. The new Regal 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 2012.
Asexual reproduction of the new Regal Geranium plant by vegetative
terminal cuttings in a controlled greenhouse environment in
Dresden, Germany since October, 2012 has shown that the unique
features of this new Regal Geranium plant 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 combinations of environmental conditions and cultural
practices. The phenotype may vary somewhat with various
environmental conditions 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 `Regpurstr`. These
characteristics in combination distinguish `Regpurstr` as a new and
distinct Regal Geranium plant: 1. Upright, outwardly spreading and
uniformly mounded plant habit. 2. Vigorous growth habit. 3. Freely
basal branching habit. 4. Early and freely flowering habit. 5.
Purple and white bi-colored flowers. 6. No required cooling
treatment for flower development.
Plants of the new Regal Geranium differ primarily from plants of
the parent selections in flower color. In addition, plants of the
new Regal Geranium are more uniform than plants of the parent
selections.
Plants of the new Regal Geranium can also be compared to plants of
the Pelargonium grandiflorum `Regwey`, disclosed in U.S. Plant Pat.
No. 26,258. In side-by-side comparisons conducted in Dresden,
Germany, plants of the new Regal Geranium differ from plants of
`Regwey` in the following characteristics: 1. Plants of the new
Regal Geranium have slightly longer internodes than plants of
`Regwey`. 2. Flowers of plants of the new Regal Geranium have
narrower petals than flowers of plants of `Regwey`. 3. Plants of
the new Regal Geranium and `Regwey` differ in lower petal color as
plants of `Regwey` have white-colored lower petals. 4. Plants of
the new Regal Geranium have shorter peduncles and pedicels than
plants of `Regwey`.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall
appearance of the new Regal 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 Regal
Geranium plant.
The photograph comprises a side perspective view of a typical
flowering plant of `Regpurstr` grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations,
measurements and values describe plants grown during the winter,
spring and summer in 19-cm containers in a glass-covered greenhouse
in Dresden, Germany and under cultural practices typical of
commercial Regal Geranium production. During the production of the
plants, day temperatures averaged 18.degree. C., night temperatures
averaged 16.degree. C. and light levels ranged from 15 kilolux to
100 kilolux. Plants were five months old when the photograph was
taken and nine 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.
