Claims
I claim:
1. A new and distinct variety of poinsettia plant designated
`WEL19375` as illustrated and described herein.
Description
Genus and species: Euphorbia pulcherrima.
Variety denomination: `WEL19375`.
CROSS REFERENCE TO RELATED APPLICATION
An application for Community Plant Variety Rights for the instant
variety was filed on Nov. 22, 2018, and has application number
2018/3063, the entire contents of which are incorporated herein by
reference.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of
poinsettia, botanically known as Euphorbia pulcherrima and
hereinafter referred to by the variety name `WEL19375`. `WEL19375`
was derived from a naturally occurring mutation of an unknown
variety within a proprietary stock of a range of varieties in a
greenhouse in Kerken, Germany.
In November 2015, a single plant was selected in Kerken, Germany.
In December 2015, `WEL19375` was first asexually propagated by
vegetative apical cuttings. `WEL19375` was found to reproduce true
to type in successive generations of asexual propagation via
vegetative apical cuttings in Stuttgart, Germany.
SUMMARY
The following are the most outstanding and distinguishing
characteristics of this new variety when grown under normal
horticultural practices in Stuttgart, Germany. 1. Red bracts with
white spots; and 2. Very good keeping quality.
DESCRIPTION OF THE PHOTOGRAPH
This new poinsettia plant is illustrated by the accompanying
photograph which shows an overall view of the whole plant. The
photograph is of a plant approximately 10 weeks old grown indoors
in Stuttgart, Germany in November 2018. The colors shown are as
true as can be reasonably obtained by conventional photographic
procedures.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `WEL19375`. The data which define these
characteristics were collected from asexual reproductions carried
out in Stuttgart, Germany. Data was collected on plants aged
approximately 20 weeks-old after potting and grown in a glass
greenhouse in Stuttgart, Germany in December 2018. Color references
are to The R.H.S. Colour Chart of The Royal Horticultural Society
