H. cooperi var. dielsiana is species from cooperi group with virtually no leaf awn and very rounded leaf end, keel and margin, some locality forms have margin spines. It is slowly proliferating species. Rosette is 5 - 10 cm in diameter and in cultivation can reach almost 15 cm. It grows on flat grassy area amongst stones or on low slopes.

Bayer includes under this variety plants from Somerset East area. Scott has described H. joeyae from locality near Eastpoort. These plants are very atractive and popular in collections. I have visited this locality in 2003 and 2012 and most of the plants are gone - without any visible reason they cleaned with buldozzer  most of the hill slope. When I revisited the site recently after 9 year - nothing was done with this field and only grass is there...sad story.
Only few bits of H. cooperi var. dielsiana are surviving under the bushes.

H. cooperi var. dielsiana in cultivation can be grown without any problems, they can grow quite large in greenhouse. They stay usually solitary, so the propagation should be done by seeds.
