Claims
I claim:
1. A new and distinct cultivar of Dianthus plant named `WP19 PIE65`
as described and illustrated herein.
Description
Genus and species: Dianthus allwoodii hort.
Variety denomination: `WP19 PIE65`.
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 allwoodii hort. and will be referred to hereinafter by
the cultivar name `WP19 PIE65`.
`WP19 PIE65` is a complex hybrid plant that is the product of a
long-term breeding program conducted in a cultivated area of
Ashcombe Road, Dawlish, Devon, United Kingdom. `WP19 PIE65` was
selected in 2016 for its large single vibrant crimson flowers,
medium clove-like fragrance and glaucous blue-green foliage.
`WP19 PIE65` 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 `GI14415`
(unpatented and unreleased) and the female parent is Dianthus code
name `GI116` (unpatented and unreleased). The male parent and
female parent had both been grown within the inventor's stock of
breeding lines.
Asexual reproduction of `WP19 PIE65` was first accomplished in 2016
in a cultivated area of Ashcombe, United Kingdom using the
propagation method of shoot cuttings. `WP19 PIE65` 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 PIE65`.
`WP19 PIE65` 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 PIE65` exhibits a compact
mounding habit. 2. `WP19 PIE65` bears large single vibrant crimson
flowers. 3. The petals of `WP19 PIE65` are flat. 4. `WP19 PIE65`
blooms from May through October. 5. The flowers of `WP19 PIE65`
exhibit a medium, clove-like fragrance. 6. `WP19 PIE65` exhibits
glaucous blue green foliage. 7. At maturity, the height of the
foliage mound of `WP19 PIE65` is 40 cm, and the width is 30 cm to
35 cm. 8. `WP19 PIE65` is perennial and is hardy at least to minus
15.degree. Centigrade. 9. `WP19 PIE65` 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 PIE65` 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 PIE65`.
FIG. 1 depicts an entire flowering plant of `WP19 PIE65`.
FIG. 2 depicts a close-up view of the flower of `WP19 PIE65`.
The photograph in FIG. 1 was taken in May 2019 from a plant which
had been grown outdoors in a 2-gallon container in Oxnard, Calif.
The photograph in FIG. 2 was taken in May 2018 from a plant which
was growing in the inventor's greenhouse in Devon, United Kingdom.
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 LINES AND KNOWN VARIETY
`WP19 PIE65` is distinguishable from the male parent as follows.
The flower color of `GI14415` is light to medium magenta with no
band. The foliage mound of `GI14415` is slightly higher with
slightly broader leaves than the foliage of `WP19 PIE65`. Both
varieties are of similar flowering height.
`WP19 PIE65` is distinguishable from the female parent as follows.
The female parent `GI116` bears dark pink flowers and is taller
overall than `WP19 PIE65` when both varieties are grown
outside.
The variety of Dianthus considered to most closely resemble `WP19
PIE65` is Dianthus Plant Named `WP17 PIE54` (U.S. Plant Pat. No.
30,245). In comparison with `WP17 PIE54`, `WP19 PIE65` bears single
vibrant crimson flowers. Whereas the foliage habit of `WP19 PIE65`
is tight and compact, the foliage habit of `WP17 PIE54` is loose
