Claims
I claim:
1. A new and distinct variety of Hydrangea plant designated
`COUFLORI` as illustrated and described herein.
Description
Genus and species: Hydrangea paniculata.
Variety denomination: `COUFLORI`.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of
Hydrangea plant, botanically known as Hydrangea paniculata, and
hereinafter referred to by the variety name `COUFLORI`. `COUFLORI`
originated from an open pollination in France between two un-named
and unknown Hydrangea paniculata parents. Seeds from the
open-pollination were taken from the female parent and sown and a
single plant was chosen in March 2013.
`COUFLORI` was first propagated in July 2015 in France. `COUFLORI`
was found to reproduce true to type in successive generations of
asexual propagation via softwood cuttings.
SUMMARY
The following are the most outstanding and distinguishing
characteristics of this new variety when grown under normal
horticultural practices in Boskoop, The Netherlands. 1. White
flowers tinged with red-purple; and 2. Having and obovate plant
shape with a broad-spreading habit.
DESCRIPTION OF THE PHOTOGRAPHS
This new Hydrangea plant is illustrated by the accompanying
photographs which shows the plant's overall plant habit including
form, and foliage. Photos were taken in August 2021 in Boskoop, The
Netherlands. The colors shown are as true as can be reasonably
obtained by conventional photographic procedures.
FIG. 1 shows the overall plant habit of `COUFLORI`, including
flowers, and foliage.
FIG. 2 shows a close-up of the flowers.
FIG. 3 shows a close-up of an individual leaf.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `COUFLORI`. The data which define these
characteristics were collected from asexual reproductions carried
out in Boskoop, The Netherlands. Data was collected on two-year old
plants grown outdoors in a 19 cm circular pot The Netherlands in
August 2021. The range of day temperatures was 16.degree. C. to
26.degree. C. and the range of night temperatures was 8.degree. C.
