Description (Jepson,

  • Monocotyledon
    • Monocots are a major lineage of flowering plants; see family for general characteristics
  • Butcher’s Broom Family (Ruscaceae)
  • Perennial herb
    • Grows from rhizomes (underground, horizontal stems); often forms colonies
  • Stems unbranched, erect or arching, zig-zagging near the tip
  • Leaves
    • Alternate (1 leaf at each junction with stem)
    • Lance-shaped to elliptic, with smooth edges (entire)
    • Prominent parallel veins
    • Clasping the stem (sessile)
  • Flowers
    • Inflorescence (flower arrangement) is a raceme (unbranched stem with stalked flowers opening from the bottom up), growing from the plant’s tip, of 5-15 white, widely-spaced, star-shaped flowers
    • Each radially-symmetrical flower has 3 petals and 3 sepals (outer flower parts), in 2 separate whorls, similar in appearance and collectively called tepals
      • 6 stamens (male flower parts) are slightly shorter than the tepals
      • Ovary superior (attached above other flower parts)
  • Fruit is a berry (a usually multi-seeded fruit with a fleshy ovary wall), red-striped while maturing, red-purple to black at maturity
  • Height to 28 in.


  • Native to California
    • Grows in moist woodlands and along stream banks
    • See Calflora for statewide observations of this plant
  • Outside California, grows across much of North America, from Alaska to California in the west and from Newfoundland to the central Appalachian Mountains in the east
  • Grows at elevations to 7,800 ft.

Uses (San Mateo County Parks prohibits removal of any natural material)

  • Wildlife
    • Flowers pollinated by bees, flies, and beetles
    • Fruit eaten by numerous bird species, as well as small rodents
  • Native people
    • Fruit eaten
  • CAUTION – berries are edible, but large quantities have a laxative effect

Name Derivation

  • Maianthemum (my-AN-the-mum) – from the Greek for “May flower,” referring to its blooming season
  • stellatum (stel-LAY-tum) – from the Latin stella, “star,” referring to the flower shape
  • Slim false Solomon’s seal
    • False Solomon’s seal – derives from the similarity of the leaves to the “true” Solomon’s seal (Polygonatum species; see below)
    • Slim – due to the simplicity of the flowers in the inflorescence and/or to the leaves, which are narrower than those of fat false Solomon’s seal (M. racemosum)

  • Geophytes (e.g. plants growing from bulbs, corms, rhizomes, or enlarged taproots) are well adapted to survive fire, our Mediterranean climate’s long, dry summers, and extended droughts
    • Above-ground growth dies back after flowering, while underground the plant survives with stored water and nutrients
  • Slim false Solomon’s seal has seen several changes in taxonomy
    • Previously listed in Lily family
    • Genus name changed from Smilacina to Maianthemum
  • “True” Solomon’s seal (Polygonatum species) does not grow natively in the Western states
    • Bell-like flowers hang in clusters from the leaf stalk
    • Berries are poisonous
    • Common name usually explained as referring to the large, circular seals (leaf stalk scars) on the rhizomes (Missouri)
