Description (Jepson, PlantID.net)

    • Eudicotyledon
      • Eudicots are a major lineage of flowering plants; see family for general characteristics
    • Sunflower Family (Asteraceae)
    • Annual or biennial herb
    • Leaves
      • Mostly narrow, oblong to lance-shaped, with wavy edges
      • May attach directly to stem (sessile)
      • Sometimes with woolly, glandular (sticky) hairs
      • Aromatic
    • Flowers
      • Inflorescence (flower arrangement) of branched, open (loose) sets of flowerheads
      • Each disciform flowerhead (see Sunflower family) is tightly packed with minute, yellow flowers
        • 100-140 female (pistillate) peripheral flowers with reduced or missing rays
        • 7-12 bisexual central disk flowers
      • Flowerheads are surrounded by rows of whitish, paper-like phyllaries (vase-like floral bracts, collectively called the involucre), like the wrapping around a flower bouquet
      • Ovary inferior (below the attachment of other flower parts)
    • Fruit is an achene (a single-seeded, dry fruit that does not split open) with a pappus of bristles
    • Height 2-4 ft.

    Distribution

      • Native to California
        • Grows in forests, foothill woodlands, and chaparral
        • See Calflora for statewide observations of this plant
      • Outside California, grows from Oregon to Baja California, Mexico
      • Grows at elevations between 200 and 2,600 ft.

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

        • Insect pollinated
        • Larval plant for the American painted lady (Vanessa virginiensis) butterfly
        • Native people used an infusion of the plant to treat colds and stomach pain; leaves were used as a poultice for burns, bruises, and cuts

        Name Derivation

          • Pseudognaphalium (soo-doe-na-FAY-lee-um) – literally, false Gnaphalium, referring to a superficial resemblance of plants in this genus to those in the genus Gnaphalium
            • Gnaphalium, from the Greek gnaphalon, “a lock of wool,” referring to the woolly leaves
          • Cudweed – commonly used worldwide for a number of plants in the Sunflower family, especially those in the genera Pseudognaphalium and Gnaphalium

          Notes

            • Aromatic leaves deter browsing
              • Some people smell maple syrup; others smell cumin: judge for yourself by rubbing the leaves – no need to pick them!
            • Bristles on fruit help dispersal by wind or animals
            • Floral bracts (phyllaries) remain on the plant long after flowering and open outward as they dry, appearing like petals; thus, the flowers seem to be “everlasting”
              • Everlasting is another common name for plants in this and related genera, collectively called the Everlasting tribe
            • What distinguishes the genus Pseudognaphalium from the related genus Gnaphalium (not found in Edgewood)?
              • Pseudognaphalium species are generally erect plants that grow in dry habitats
              • Gnaphalium species are low-growing, spreading or prostrate plants that grow in moist, often coastal habitats
