Claims
What is claimed is:
1. A new and distinct variety of rose plant of the shrub class,
substantially as herein shown and described.
Description
Classification: The present invention relates to a new Rosa hybrida
shrub of the market class `English Rose`.
Variety denomination: The new plant has the varietal denomination
`AUSwhirl`.
CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority to European CPVO 2014/2054,
filed Aug. 21, 2014.
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of shrub rose
plant named `AUSwhirl`, which was originated from the
cross-pollination of the two `unnamed` and unpatented seedlings of
Rosa hybrida.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a rose
variety having a yellow bloom with a strong, unfading color, the
petals of which are informal with a neat outer ring, and that has a
strong fragrance that smells distinctly of lemon, and that also has
a growth that is low and rounded with shiny foliage.
SUMMARY OF THE INVENTION
Among the features which distinguish the new variety from others
presently available and commercial rose cultivars known to the
inventor is the following combination of characteristics: blooms
having an unfading, strong yellow color with an informal
arrangement of petals within a neat outer ring of petals, and low
rounded growth that has shiny foliage, and a strong lemon
fragrance.
Asexual reproduction of the new variety by budding as performed at
Bowling Green Lane in Albrighton, Britain shows that the foregoing
and other distinguishing characteristics come true to form and are
established and transmitted through succeeding asexual
propagations. `AUSwhirl` may be asexually propagated by budding.
The budding successfully occurred on the plant/rootstock Rosa
dumetorum `Laxa` for the observed plants.
COMPARISON WITH PARENTS
The seed and pollen parents of `AUSwhirl` are two unnamed
seedlings. The new rose may be distinguished from its seed parent,
by the following combination of characteristics: the seed parent is
more disease prone with larger pink flowers. The new rose may be
distinguished from its pollen parent, by the following combination
of characteristics: the parent is a deeper shade of yellow, with
larger flowers and is more disease-prone.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivar to the new variety is
the `AUSmol` (U.S. Plant Pat. No. 9,524) and `AUSbaker`
(unpatented). The new rose may be distinguished from the `AUSmol`
and `AUSbaker` varieties by the following combination of
characteristics: the `AUSmol` (110-120) and `AUSbaker` (110) roses
have more petals than `AUSwhirl` (77). The arrangement of petals
also differs, in `AUSwhirl` the petal arrangement is informal
whereas for `AUSmol` it is a regular rosette formation and for
`AUSbaker` the blooms are quartered. Finally, `AUSwhirl` forms a
low, rounded shrub whereas `AUSmol` is upright and short, and
`AUSbaker` is tall and will grow as a climber.
BRIEF DESCRIPTION OF ILLUSTRATION
The accompanying photograph illustrates the new variety and shows
the flowering thereof from bud to full bloom depicted in color as
nearly correct as it is possible to make in a color illustration of
the character. Throughout this specification, color references
and/or values are based upon the Colour Chart of The Royal
Horticultural Society (2001) except where common terms of color
definition are employed.
DESCRIPTION OF THE NEW VARIETY
Observations of budded `AUSwhirl` specimens were made in
Albrighton, Wolverhampton, United Kingdom. The following
description is of 1 year-old potted rose plants of the new variety
grown in a garden environment in Albrighton, Britain in the month
of June. Phenotypic expression may vary with environmental,
cultural and climatic conditions, as well as differences in
conditions of light and soil.
