I am growing M. cyllenium, M. friwaldskyanum, M. incanum, and M. suppinum
here in zone 5a.  This is the first year, so I cannot truly comment on winter
hardiness or on suitability for ground covers.

Arrowhead alpines carries M. incanum and  M. vulgare in their seed section, so
you should search all the specialty catalogs in the nursery trade, I think.

If you need a common name, most of them are referred to as horehounds.
