Claims
What is claimed is:
1. A new and distinct variety of rose plant of the shrub class
suitable for repeat flower production, substantially as herein
shown and described.
Description
Classification: The present invention relates to a new Rosa hybrida
shrub.
Variety denomination: The new plant has the varietal denomination
`AUSjosiah`.
CROSS-REFERENCE TO RELATED APPLICATIONS
The current application claims priority to a United Kingdom
Breeder's Right Certificate Application No. AFP 5/2116, filed Feb.
11, 2010, the disclosure of which is incorporated herein by
reference.
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of shrub rose
plant named `AUSjosiah`, which was originated by crossing two
unnamed, unpatented varieties of Rosa hybrida.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce an
exceptionally vigorous flowering variety having delicate individual
blooms of a soft rose pink with a lovely fragrance, which is fruity
on the outer petals and clove in the center.
SUMMARY OF THE INVENTION
Among the features which distinguish the new variety from other
presently available and commercial rose cultivars known to the
inventor is the following combination of characteristics: beautiful
and delicate individual blooms of a soft rose pink with a lovely
fragrance which is fruity on the outer petals with clove in the
center, exceptionally vigorous growth sending up many shoots from
the base and forming a large rampant shrub, and ample foliage that
is dark green and glossy.
Asexual reproduction of the new variety by budding as performed in
greenhouses 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. `AUSjosiah` may be asexually propagated by budding
and grafting. The budding and grafting successfully occurred on the
plant/rootstock Rosa cv. `Dr. Huey` in the United States and on the
plant/rootstock Rosa dumetorum cv. `Laxa` in the United
Kingdom.
COMPARISON WITH PARENTS
The new rose may be distinguished from its seed parent, by the
following combination of characteristics: whereas the seed parent
is not as disease resistant and has larger more open blooms,
`AUSjosiah` bears individual blooms of a soft rose pink with a
lovely fragrance which is fruity on the outer petals with clove
scents in the center.
The new variety may be distinguished from its pollen parent, by the
following combination of characteristics: whereas the pollen parent
is an overall poorer quality plant, `AUSjosiah` is exceptionally
vigorous.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivar to the new variety is
the `AUSrumba` (U.S. Plant Pat. No. 17,500). The new rose may be
distinguished from the `AUSrumba` variety by the following
combination of characteristics: the `AUSrumba` is a medium height
rounded shrub, whereas the `AUSjosiah` is a vigorous shrub, the
`AUSrumba` produces blooms having a fragrance of strong old rose
with a hint of myrrh, compared to `AUSjosiah`, which produces a
fruity fragrance with clove. In addition, the bud color of the
`AUSjosiah` is pink, and the buds of `AUSrumba` are
apricot-colored.
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.
