Claims
I claim:
1. A new and distinct cultivar of perennial Carnation or Pinks,
Dianthus plant named `Apple Slice` as herein described and
illustrated, with fragrant highly double flowers, petals with a
central rose pink zone surrounded on the outside and usually
bisected down the middle with a magenta border, tolerant of high
temperatures, resistant to center die out and suitable as a garden
ornamental, potted plant and for cut flower arrangements.
Description
Botanical denomination: Dianthus hybrid.
Cultivar designation: `Apple Slice`.
BACKGROUND OF THE INVENTION
The present invention relates to the new and distinct cultivar of
Dianthus or Pinks from the genus Dianthus and assigned the cultivar
name `Apple Slice`. The new plant was the result of an intentional
cross in May of 2006 by Kevin A. Hurd between `Double Spotty` U.S.
Plant Pat. No. 13,884 as the seed parent and `Devon Siskin` U.S.
Plant Pat. No. 14,377 (more often known as `Raspberry Swirl`) as
the pollen parent. The new hybrid was first isolated from trials at
a nursery in Zeeland, MI during the summer of 2007. Dianthus `Apple
Slice` has been asexually propagated at the same nursery in
Zeeland, MI using traditional shoot tip cutting procedures and
found to reproduce plants that are identical and exhibit all the
characteristics of the original plant.
SUMMARY OF THE INVENTION
The present invention has not been evaluated under all possible
environmental conditions. The phenotype may vary with variations in
environment including: growing temperature, available sunlight,
nutrients, water, etc. without a change in the genotype of the
plant. The new plant is distinct from its parents and all other
Dianthus known to the applicant in the following combined traits:
1. Double flowers with high petal counts. 2. Unique floral color
pattern. 3. High heat tolerance. 4. Floriferous habit. 5. Vigorous
growth and excellent habit. 6. Compact, distinctly blue-green
foliage.
BRIEF DESCRIPTION OF THE DRAWINGS
The photographs of the new invention demonstrate the overall
appearance of the plant including the unique traits. The colors are
as accurate as reasonably possible with color reproductions. Some
slight variation of color may occur as a result of lighting
quality, intensity, wavelength, direction or reflection.
FIG. 1 shows the new plant in flower.
FIG. 2 shows a close-up of the flower and bud.
FIG. 3 shows the dissected flower of the new plant together with
capsule and seeds.
DETAILED DESCRIPTION OF THE PLANT
The following detailed description of the new plant is based on
observations of two-year old plants in open-field, full-sun
conditions in Zeeland, MI with supplemental watering, light
additions of fertilizer and free of other plant growth regulators.
All color usage is in reference to the 2001 edition of The Royal
Horticultural Colour Chart except where common dictionary terms are
used. Botanical classification: Dianthus hybrid. Parentage: `Double
Spotty` (female) times `Raspberry Swirl` (male). Plant description:

Nodes.--4 mm across, RHS N134A. Internodes.--4 to 5 cm apart.
Inflorescence: Type.--Terminal, cymose, erect. Flowers per
stem.--Usually 4 to 6. Pedicel.--Glaucous, glabrous, terete.
Pedicel size.--Usually 3 to 4 cm long and 2 mm diameter. Pedicel

double, symmetrical. Dimension.--4.0 to 4.5 cm across and extending
about 1.5 cm above calyx. Flower bud shape.--Rhomboid to terete.
Flower bud size one day prior to opening.--About 2 cm long and 1 cm

completely within the calyx), obovate, apex dentate with dentations
2 mm deep, bearded with minute hairs mostly on the center of the
adaxial surface, bent outwardly to nearly a ninety degree angle;
dark wine-colored margin circle on adaxial side about 5 mm thick;
variable center stripe either continuous to 2 mm wide, broken or

high temperatures and some drought once established. Hardiness at
least from USDA zone 4 through 9. Comparison varieties: The new
plant has more petals, with wider and deeper ruby petal margins,
and deeper pink petal centers than either parent. The most closely
known cultivars are Dianthus `Cranberry Ice` U.S. Plant Pat. No.
18,342 which is similar in petal color but has only a single row of
petals and copending application Dianthus plant named `Coconut
Punch` which has much lighter (whiter and less pink) adaxial petal
limb centers and abaxial petal limb sections.
