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
`AUSearnshaw`.
CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority to UK Varietal Plant Patent
5/2140, filed Sep. 21, 2018.
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of shrub rose
plant named `AUSearnshaw`, 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 bushy rose
variety having a strong, healthy upright growth with distinctive
blooms, which are neat and rather flat, each bloom being a lovely
soft pink with a yellow-apricot center with a button eye, and
having a strong fragrance with begins as Tea and becomes Old
Rose.
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: a healthy
bushy shrub with strong upright growth, blooms of a soft pink color
with a yellow-apricot center and a button eye, and a strong
fragrance that starts as Tea and develops into an Old Rose.
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. `AUSearnshaw` may be asexually propagated by budding.
The budding successfully occurred on an unpatented plant/rootstock
Rosa dumetorum `Laxa` for the observed plants.
COMPARISON WITH PARENTS
The maternal and paternal parents of `AUSearnshaw` are two unnamed
seedlings. The new rose may be distinguished from its maternal
parent, by the following combination of characteristics: the
maternal parent is a shorter bush and has uniformly deep pink
flowers compared to the soft pink, apricot-centered blooms of
`AUSearnshaw`. The new rose may be distinguished from its pollen
parent, by the following combination of characteristics: the
paternal parent has a larger growth and its blooms are more cupped
with fewer petals than `AUSearnshaw`.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivar to the new variety is
the `AUSrimini` (U.S. Plant Pat. No. 18,716). While the color of
both are a similar soft pink, the new rose may be distinguished
from the `AUSrimini` based on the apricot-colored center of
`AUSearnshaw`. It may also be distinguished by the fact that the
growth habit differs in that `AUSrimini` is a short climber whereas
`AUSearnshaw` is a shrub.
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 `AUSearnshaw` specimens were made at the
nursery at David Austin Roses Limited in Albrighton, Wolverhampton,
United Kingdom. The following description is of 4 year-old 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.
