Botanical classification: Delosperma nubigenum.
Variety denomination: ‘S3yel’.
This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2023/0835 filed on Apr. 6, 2023, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The Applicant received the information for the Plant breeders' rights application directly from the Inventor. This application is co-pending with U.S. Plant Patent Applications filed for plants derived from the same breeding program that are entitled Delosperma Plant Named ‘S3ora’ (U.S. Plant Pat. No. 18/441,147)*, Delosperma Plant Named ‘S3red’ (U.S. Plant Pat. 18/441,197)*, Delosperma Plant Named ‘S3ros’ (U.S. Plant Pat. No. 18/441,246), and Delosperma Plant Named ‘S3whi’ (U.S. Plant Pat. No. 18/441,346).
The present invention relates to a new and distinct cultivar of Delosperma plant, botanically known as Delosperma nubigenum ‘S3yel’ and will be referred to hereinafter by its cultivar name, ‘S3yel’. The new cultivar of Delosperma is an evergreen perennial grown for container and landscape use.
The new cultivar was derived from a controlled breeding program conducted by the Inventor in Katsuta-Gun, Okayama-Pref., Japan. The overall purpose of the breeding program was to develop new cultivars of Delosperma plants with short stem internodes, good branching with dense growth habits, neat growing habits with suitability for growing in small containers, and very high flower counts.
‘S3yel’ was selected in the Inventor's trial garden in October of 2019 as a single unique plant from amongst the seedlings derived from crosses made in 2016 between unnamed and unpatented plants from the Inventor's breeding program. Seeds were pooled from the crosses and therefore the exact parentage is unknown.
Asexual propagation of the new cultivar was first accomplished by stem cuttings in October of 2019 by the Inventor in Katsuta-Gun, Okayama-Pref., Japan. Asexual propagation by stem cuttings has determined the characteristics of the new cultivar are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘S3yel’ as a unique cultivar of Delosperma.
‘S3yel’ can be most closely compared to the Delosperma cultivars ‘WOW2011-1’ (U.S. Plant Pat. No. 25,684) and ‘WOWDAY2’ (U.S. Plant Pat. No. 25,645). ‘WOW2011-1’ is similar to ‘S3yel’ in having petals that are yellow, a floriferous habit, and in being the same species. ‘WOW2011-1’ differs from ‘S3yel’ in having larger sized flowers, yellow-green petaloids, longer internodes, and less suitability for use in small containers. ‘WOWDAY2’ is similar to ‘S3yel’ in having a floriferous habit, yellow petaloids, and in being the same species. ‘WOWDAY2’ differs from ‘S3yel’ in having flower petals that are red on the outer region, less suitability for use in small containers, and longer internodes.
‘S3yel’ can also be compared to co-pending cultivars of Delosperma nubigenum. They are all similar to ‘S3yel’ in plant habit in having short internodes and suitability for growing in small containers. ‘S3ora’ differs from ‘S3yel’ in having flowers with petals that are orange on the outer region and yellow towards the center of the flower surrounding yellow petaloids. ‘S3red’ differs from ‘S3yel’ in having flowers with petals that are magenta pink on the outer region and white towards the center of the flower surrounding yellow-white petaloids. ‘S3ros’ differs from ‘S3yel’ in having flowers with petals that are violet on the outer region and white towards the center of the flower surrounding white petaloids. ‘S3whi’ differs from ‘S3yel’ in having flowers with petals that are white surrounding white-yellow petaloids.
The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. Disclosures include but may not be limited to website listings by Plantipp, Kientzler Jungpflanzen, FlorSAIKA, and Express Seed Company.

The following is a detailed description of 3-month-old plants of the new cultivar as grown outdoors in 12-cm pots in Gensingen, Germany. 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.
