Apparently the plant has several "common names" in english. I referred to common names on another thread you started about this plant. Common names are simply that, names that people commonly use for a plant. Sometimes several plants have the same common name. Sometimes the common name is confusing, as I mentioned before about 'heavenly bamboo', as it is not a bamboo.
I don't call this plant anything but Stachys affinis, as I tend to only use the latin names for plants.
