Claims
It is claimed:
1. A new and distinct Regal Geranium plant named `Regarwhite` as
illustrated and described.
Description
Botanical designation: Pelargonium grandiflorum.
Cultivar denomination: `REGARWHITE`.
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
`Regarwhite`.
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 of two unidentified proprietary selections of
Pelargonium grandiflorum, not patented, during the summer of 2015.
Seed was collected from a number of potential parent plants,
combined and sown. The new Regal Geranium plant was discovered and
selected by the Inventor as a single flowering plant from within
the progeny of the stated mass cross-pollination in a controlled
greenhouse environment in Dresden, Germany during the spring of
2016.
Asexual reproduction of the new Regal Geranium plant by vegetative
terminal cuttings in a controlled greenhouse environment in
Dresden, Germany since October, 2016 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 `Regarwhite`. These
characteristics in combination distinguish `Regarwhite` as a new
and distinct Regal Geranium plant: 1. Upright, outwardly spreading
and uniformly mounded plant habit. 2. Moderately vigorous growth
habit. 3. Freely basal branching habit. 4. Early and freely
flowering habit. 5. White-colored flowers. 6. No required cooling
treatment for flower development.
Plants of the new Regal Geranium can be compared to plants of the
Pelargonium grandiflorum `Camwhimp`, not patented. In side-by-side
comparisons, plants of the new Regal Geranium differ from plants of
`Camwhimp` in the following characteristics: 1. Plants of the new
Regal Geranium are larger than plants of `Camwhimp`. 2. Plants of
the new Regal Geranium have larger leaves than plants of
`Camwhimp`. 3. Plants of the new Regal Geranium have larger flowers
with larger petals than plants of `Camwhimp`.
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 is a side perspective view of a
typical flowering plant of `Regarwhite` 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 Thiendorf, 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 given a eight-week cooling treatment at
9.degree. C. to enhance flower development. Plants were five months
old when the photograph was taken and seven 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 grandiflorum `Regarwhite`. Parentage: Female, or seed,
parent.--Unidentified proprietary selection of Pelargonium
grandiflorum, not patented. Male or pollen parent.--Unidentified
proprietary selection of Pelargonium grandiflorum, not patented.
Propagation: Type.--By vegetative terminal cuttings. Time to
initiate roots, summer.--About 18 days at temperatures about
20.degree. C. Time to initiate roots, winter.--About 22 days at
temperatures about 20.degree. C. Time to produce a rooted young
plant, summer.--About four weeks at temperatures about 20.degree.
C. Time to produce a rooted young plant, winter.--About four weeks
at temperatures about 18.degree. C. Root description.--Fine,
fibrous; typically white in color, actual color of the roots is
dependent on substrate composition, water quality, fertilizer type
and formulation, substrate temperature and physiological age of
roots. Rooting habit.--Freely branching; dense. Plant description:

mounded plant habit; broad inverted triangle; densely foliated;
moderately vigorous growth habit; medium growth rate; freely basal
branching habit with about five primary lateral branches each with
five secondary lateral branches developing per plant. Plant height,
to top of leaves.--About 28 cm. Plant height, to top of
