There are plants that have been bred specifically for use in rock gardens and on graves. This includes the Saxifrage hybrid Saxifraga x arendsii. Saxifraga x arendsii is the hybrid combination Saxifraga exarata x Saxifraga granulata x Saxifraga hypnoides x Saxifraga rosacea. There are several varieties of Saxifraga x arendsii, whose flower colors range from white to deep red. Originally, several Saxifraga x arendsii varieties were bred by Georg Arends from Wuppertal-Ronsdorf; today, similar forms are also available from other breeders. These hybrids, called Moss Saxifrage by the nurseries, should not be confused with biological species from European mountains, which are called Moss Saxifrage, too.
