Claims
I claim:
1. A new and distinct cultivar of Dianthus Plant Named `WP19 VAL01`
as described and illustrated herein.
Description
Genus and species: Dianthus x allwoodii hort.
Variety denomination: `WP19 VAL01`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct cultivar of
hardy Dianthus, commonly known as Garden Pink, which is grown for
use as a flowering plant for pots and containers and for planting
in the garden and landscape. The new cultivar is known botanically
as Dianthus x allwoodii hort. and will be referred to hereinafter
by the cultivar name `WP19 VAL01`.
`WP19 VAL01` is a complex hybrid plant that is the product of a
long-term breeding program conducted in a cultivated area of
Dawlish, Devon, United Kingdom. `WP19 VAL01` was selected in 2016
for its yellow semi-double flowers, medium clove-like fragrance and
glaucous blue-green foliage.
`WP19 VAL01` arose and was selected as a seedling which resulted
from the controlled pollination of two prior selections of
Dianthus. The male parent is Dianthus code name `VAL 13.01`
(unpatented and unreleased) and the female parent is Dianthus code
name `VAL 09.01` (unpatented and unreleased). The male parent and
female parent had both grown within the inventor's stock of
breeding lines.
Asexual reproduction of `WP19 VAL01` was first accomplished in 2016
in a cultivated area of Dawlish, United Kingdom using the
propagation method of shoot cuttings. `WP19 VAL01` has been
determined to be stable and reproduces true to type in successive
generations of asexual propagation.
SUMMARY
The following traits have been repeatedly observed and represent
the characteristics of the new Dianthus cultivar `WP19 VAL01`.
`WP19 VAL01` has not been tested under all possible conditions and
phenotypic differences may be observed with variations in
environmental, climatic and cultural conditions, however, without
any variance in genotype. 1. `WP19 VAL01` exhibits a dense, compact
mounding habit. 2. `WP19 VAL01` bears semi-double yellow flowers.
3. The petals of `WP19 VAL01` are wavy. 4. `WP19 VAL01` blooms from
May through October. 5. The flowers of `WP19 VAL01` exhibit a
medium clove-like fragrance. 6. `WP19 VAL01` exhibits glaucous
blue-green foliage. 7. At maturity, the height of the foliage mound
of `WP19 VAL01` is 35 cm, and the width is 23 cm. 8. `WP19 VAL01`
is perennial and is hardy at least to minus 15.degree. Centigrade.
9. `WP19 VAL01` is suitable for use as a flowering plant in pots
and containers, and for use as a cut flower and in bouquets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs illustrate the overall
appearance of the new Dianthus variety `WP19 VAL01` showing colors
as true as it is reasonably possible to obtain in colored
reproductions of this type. Colors in the photographs may differ
from the color values cited in the detailed botanical description,
which accurately describe the actual colors of the new variety
`WP19 VAL01`.
FIG. 1 depicts an entire flowering plant of `WP19 VAL01`.
FIG. 2 depicts a close-up view of the flower of `WP19 VAL01`.
Photographs were taken in May 2020 from a 9 months old plant which
has been grown in an unheated greenhouse in Dawlish, United Kingdom
in a 3-liter container. No chemicals were used to treat the plants.
All photographs were made using conventional techniques and
although colors may appear different from actual colors due to
light reflectance they are as accurate as possible by conventional
photography.

COMPARISON WITH PARENTAL LINE AND KNOWN VARIETY
`WP19 VAL01` is distinguishable from the male parent as follows.
The flower color of `VAL 13.01` is bright orange with white stripes
and flowering height is much higher.
`WP19 VAL01` is distinguishable from the female parent as follows.
The female parent `VAL 09.01` bears semi-double salmon flowers with
white flecks. The vegetative part of `VAL 09.01` is also more open
than `WP19 VAL01`.
The variety of Dianthus considered to most closely resemble `WP19
VAL01` is Dianthus Plant Named `Devon Cream` (unpatented). Both
`Devon Cream` and `WP19 VAL01` are cold-hardy varieties with
similar glaucous blue green foliage and with flower colors in the
cream-yellow range. In comparison, the flower color of `Devon
Cream` is cream-yellow with pale pink stripes, whereas the flower
color of `WP19 VAL01` is distinctly self-yellow. In addition,
whereas the plant habit of `WP19 VAL01` is tight and compact, the
plant habit of `Devon Cream` is loose and open, and plants of
`Devon Cream` bear much taller flower stems.
