Claims
It is claimed:
1. A new and distinct variety of Delosperma plant named `DE18-162`
as described and illustrated herein.
Description
Botanical classification: Delosperma cooperi.
Variety denomination: `DE18-162`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Delosperma plant, botanically known as Delosperma cooperi
`DE18-162` and will be referred to hereinafter by its cultivar
name, `DE18-162`. The new cultivar of Delosperma is an herbaceous
perennial grown for container and landscape use.
The new cultivar was derived from a controlled breeding program
conducted by the Inventor in Ichinimiya-City, Aichi-Pref, Japan.
The overall purpose of the breeding program was to develop new
cultivars of Delosperma plants with low-growing and well-spreading
growth habits combined with long flowering periods and a unique
range of flower colors.
`DE18-162` arose from a crosses made by the Inventor between
unnamed and unpatented proprietary plants of Delosperma cooperi
from his breeding program. Seeds were pooled from the crosses and
therefore the exact parentage is unknown. `DE18-162` was selected
in 2015 as a single unique plant amongst the resulting
seedlings.
Asexual propagation of the new cultivar was first accomplished by
softwood cuttings in 2015 by the Inventor in Ichinimiya-City,
Aichi-Pref, Japan. Propagation by softwood cuttings has shown that
the unique features of the new cultivar are stable and reproduced
true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are
determined to be the characteristics of the new cultivar. These
attributes in combination distinguish `DE18-162` as a unique
cultivar of Delosperma. 1. `DE18-162` exhibits a compact and
horizontal plant habit 2. `DE18-162` exhibits flowers that are true
pink in color. 3. `DE18-162` exhibits floriferous and long blooming
flowering habit. 4. `DE18-162` exhibits high heat tolerance.
`DE18-162` can be most closely compared to Delosperma cooperi
cultivars `Jewel of Desert Rosequartz` (U.S. Plant Pat. No. 23,452)
and `WOWDRY1` (U.S. Plant Pat. No. 26,157). `Jewel of Desert
Rosequartz` differs from `DE18-162` in having flowers that are
redder pink in color. `WOWDRY1` differs from `DE18-162` in having
flowers with petals that are magenta pink towards the apex changing
to red-pink and then yellow towards the base.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photographs illustrate the overall
appearance and distinct characteristics of the new Delosperma. The
plant in the photograph is 3 months in age as grown in a 1-liter
container in an unheated greenhouse in Noordwijkerhout, The
Netherlands.
The photograph in FIG. 1 provides a side view of `DE18-162` in
bloom.
The photograph in FIG. 2 provides a close-up view of a flower of
`DE18-162`.
The photograph in FIG. 3 provides a close-up view of the foliage of
`DE18-162`.
The colors in the photographs may differ slightly from the color
values cited in the detailed botanical description, which
accurately describe the colors of the new Delosperma.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of three month-old plants
of the new cultivar as grown in a 1-liter container in an unheated
greenhouse in Noordwijkerhout, The Netherlands. The phenotype of
the new cultivar may vary with variations in environmental,
climatic, and cultural conditions, as it has not been tested under
all possible environmental conditions. The color determination is
in accordance with The 2015 Royal Horticultural Society Colour
