When separated from Monardella odoratissima, it is a perennial wildflower found only in California, except for one subspecies which sometimes occurs in Oregon.
It produces rounded inflorescences of small, thready, bright lavender or pink flowers.
[4] Studies in preparation for new editions of the Flora of North America and The Jepson Manual showed that there was "continuous variation" between Monardella odoratissima and M. villosa.
[5] As of April 2024[update], Plants of the World Online accepted the placement of M. villosa within M. odoratissima.
This plant was used by the indigenous peoples of California as a remedy for stomach upset, respiratory conditions, and sore throat.
