A big population of Crassula helmsii grows in a pond near Schauernheim in Palatina. It originates from Australia and is used in aquariums. Some sources mention 'Australia and New Zealand' as origin, but according to other sources the plants from New Zealand shall be different to those from Australia.
In the Botanical Garden of the University of Mainz the plant ist cultivated under the wrong name Crassula aquatica (L.) SCHÖNLAND, which would be a European species.
