Abstract

A new and distinct cultivar of Delosperma plant named ‘DDDYE04-0’ is disclosed, characterized by abundant large, yellow flowers occurring throughout the plant. Plants have a low, mounding habit, and are tolerant to cold. The new variety is a Delosperma, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Delosperma cooperi.

Variety denomination: ‘DDDYE04-0’.

BACKGROUND OF THE INVENTION

The new Delosperma cultivar is a product of open pollination by the inventor at a commercial nursery in NSW, Australia. The open pollination was made in October 2016.

Various unnamed, unpatented proprietary Delosperma varieties were planted in open-pollination crossing blocks and the resulting seed bulk collected. Parent varieties are unidentified. The new variety was selected in October 2017 by the inventor in a group of seedlings at the same nursey in Cobbitty, NSW, Australia.

Asexual reproduction of the new cultivar ‘DDDYE04-0’ by terminal vegetative cuttings was first performed at a greenhouse in Cobbitty, NSW, Australia in October 2017, and has shown that the unique features of this cultivar are stable and reproduced true to type in 6 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DDDYE04-0’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DDDYE04-0’ These characteristics in combination distinguish ‘DDDYE04-0’ as a new and distinct Delosperma cultivar:

    • 1. Bright yellow flowers.
    • 2. Low, mounded habit.
    • 3. Cold tolerance to USDA Zone 5.
    • 4. Large flowers.
    • 5. Flowering throughout plant, not just on tips.
    • 6. Drought tolerance.
PARENT COMPARISON

The seed parents are not identifiable.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DDDYE04-0’ are comparable to the variety Delosperma ‘WOWD2011-1’, U.S. Plant Pat. No. 25,684. The two Delosperma varieties are similar in most horticultural characteristics, however, the new variety ‘DDDYE04-0’ differs in the following:

    • 1. The new variety has better cold tolerance than this comparator.
    • 2. The new variety flowers more in Summer than this comparator.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DDDYE04-0’ grown in a nursery in the ground. Age of the plant photographed is approximately 8 months from a rooted cutting.

FIG. 2 illustrates in full color a close up of typical blooms of ‘DDDYE04-0’.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION
