    Distribution

      • Native and endemic (limited) to California
        • Grows in serpentine soil in grasslands and open areas of woodlands, forests, and chaparral
        • 95% of plants occur on serpentine (ultramafic) soils; see Serpentine affinity rankings (Calfora per Safford and Miller 2020)
        • See Calflora for statewide observations of this plant
      • Grows at elevations to 4,300 ft.

      Uses (Picking or removing any natural material from public land is illegal)

        • Nectar and pollen source for native bees
        • Nectar source for many butterflies, including monarch (Danaus plexippus), Chalcedon checkerspot (Euphydryas chalcedona), pale swallowtail (Papilio eurymedon), western tiger swallowtail (P. rutulus), calliope fritillary (Speyeria callippe), and several species of skippers
        • Native people had many medicinal uses for this plant
          • Decoction and salve used for respiratory conditions
          • Infusion of leaves used for stomach aches
          • Poultice of plant applied to cuts made on the back to draw out ‘bad blood’ for pneumonia

        Name Derivation

          • Monardella (mon-ar-DEL-la) – refers to plants in this genus appearing to be dwarf forms of those in the genus Monarda, also in the Mint family, which includes bee balm and bergamot
            • Monarda – named after Nicholás Bautista Monardes (1493-1588), Spanish botanist and physician who studied American plants and their medicinal uses
          • villosa (vil-OH-sa) – from the Latin villosus, “shaggy” or “roughly hairy”

          Notes

            • Aromatic oils, characteristic of the Mint family, smell good to most humans, but deter many potential herbivores
            • Edgewood’s coyote mint is classified as a subspecies
              • Subspecies rank is used to recognize geographic distinctiveness, whereas variety rank is appropriate for variants seen throughout the geographic range of the species; in practice, these two ranks are not distinct

            At Edgewood

              • Grows in grasslands and in open areas in chaparral and woodlands
                • See iNaturalist for observations of this plant
                  • Note observations are for Monardella villosa
              • Flowers May – June
