Claims
It is claimed:
1. A new and distinct variety of Delosperma plant named `Wow312` as
described and illustrated herein.
Description
Botanical classification: Delosperma nubigenum.
Variety denomination: `Wow312`.
CROSS REFERENCE TO RELATED APPLICATIONS
This application is related to U.S. Plant Patents derived from the
same breeding program that are entitled Delosperma Plant Named
`WOW2011-1` (U.S. Plant Pat. No. 25,684) and Delosperma Plant Named
`Jewel of Desert Peridot` (U.S. Plant Pat. No. 23,566). This
application claims priority to European Community Plant Variety
Office (CPVO) Plant Breeder's Rights Application No. 2019/0863
filed on Apr. 4, 2019, the entire contents of which is incorporated
by reference herein.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Delosperma plant, botanically known as Delosperma nubigenum
`Wow312` and will be referred to hereinafter by its cultivar name,
`Wow312`. The new cultivar of Delosperma is an herbaceous perennial
grown for container and landscape use.
The new cultivar 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.
`Wow312` arose from crosses made by the Inventor between unnamed
and unpatented proprietary plants of Delosperma nubigenum from his
breeding program. Seeds were pooled from the crosses and therefore
the exact parentage is unknown. `Wow312` was selected in May of
2013 as a single unique plant amongst the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished by
stem cuttings in September of 2013 by the Inventor in
Ichinimiya-City, Aichi-Pref, Japan. Propagation by stem 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 `Wow312` as a unique cultivar
of Delosperma. 1. `Wow312` exhibits a low-growing plant habit. 2.
`Wow312` exhibits a long blooming period. 3. `Wow312` exhibits
flowers that have bright white petal tips, white center eye and
bright yellow in the mid-section.
`Wow312` can be most closely compared to Delosperma cooperi
cultivars `WOW2011-1` and `Jewel of Desert Peridot`. `WOW2011-1`
and `Jewel of Desert Peridot` are both similar to `Wow312` in
having yellow and white flowers. `WOW2011-1` differs from `Wow312`
in having all yellow flower petals. `Jewel of Desert Peridot`
differs from `Wow312` in having flower petals that are all yellow
with large white centers.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photographs illustrate the overall
appearance and distinct characteristics of the new Delosperma. The
photographs were taken of a 2-liter container planted with 5 plants
that were 3 months in age as grown in an unheated greenhouse in
Noordwijkerhout, The Netherlands.
The photograph in FIG. 1 provides a side view of `Wow312` in
bloom.
The photograph in FIG. 2 provides a close-up view of a flower of
`Wow312`.
The photograph in FIG. 3 provides a close-up view of the foliage of
`Wow312`.
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 2-liter containers
planted with 5 plants that were 3 months in age as grown 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 Colour Chart of The
Royal Horticultural Society, London, England, except where general
color terms of ordinary dictionary significance are used. General
