Other info. - Plants in the genus Cerastium are usually small and weedy looking, but this is an exception. It is without a doubt the showiest member of the genus in Missouri and certainly the largest-flowered. It is found mostly in the eastern Ozark region of the state. Its range in the U.S. is very limited. There are populations in Missouri, Illinois, and Pennsylvania, but it absent or considered rare everywhere else. This is a beautiful plant and would make a good garden subject.

C. velutinum has in the past been considered a subspecies of C. arvense; however, the two species apparently do not hybridize in the wild and are usually easily distinguished. Many Missouri specimens formerly assigned to C. arvense have recently been redetermined as C. velutinum. Plants found in Missouri belong to the subspecies velutinum. The subspecies villosissimum (Pennell) J.K. Morton is endemic to serpentine outcrops in Maryland, New Jersey, and Pennsylvania. It differs in its denser, broader, more persistent leaves with more dense, shaggy pubescence.
