Description (Jepson, PlantID.net)

  • Monocotyledon
    • Monocots are a major lineage of flowering plants; see family for general characteristics
  • Brodiaea Family (Themidaceae)
  • Perennial herb
    • Grows from a corm (short, solid, vertical underground stem)
  • Leaves
    • 3-10 grasslike, linear, basal leaves
    • May wither before the plant blooms
  • Flowers
    • Inflorescence (flower arrangement) is an umbel (a spoke-like flower cluster with stalks radiating from a single point) at the end of a leafless stalk (scape), with individual flower stalks (pedicels) up to 2 in. long
      • Greenish white, star-shaped flowers with brownish colored midveins
      • Fused bracts (modified leaves) at base become papery with age
    • Individual flowers have 3 petals and 3 sepals (outer flower parts), in 2 separate whorls, similar in appearance and collectively called tepals
    • 6 prominent stamens (male flower parts) may be green, blue or purple
    • Ovary superior (above the attachment of other flower parts)
  • Fruit is a capsule (a dry multi-chambered pod that splits open)
  • Height to 6 in.

Distribution

  • Native to California
    • Grows in grasslands, woodlands, and coastal scrub in alkaline, granitic, or serpentine soils
    • 50-54% of plants occur on ultramafic soils, e.g. serpentine; see ultramafic affinity rankings (Calflora per Safford and Miller 2020)
    • See Serpentine Grassland for more about Edgewood’s serpentine soil and the unique communities it supports
    • See Calflora for statewide observations of this plant
  • Outside California, grows in Baja California, Mexico
  • Grows at elevations to 7,500 ft.

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

  • Insects, including beetles, seek the nectar

Name Derivation

  • Muilla (moo-IL-a) – from the word “allium” spelled backwards, a humorous anagram referring to the plant’s superficial resemblance to onions, in the genus Allium
  • maritima (mar-IT-i-ma) – from the Latin for “coast”

Notes

  • Geophytes, e.g. plants growing from bulbs, corms, and rhizomes, are 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
  • Previously included in the Lily family

ID Tips

  • Although “muilla” is “allium” spelled backwards, implying the plant is onion-like, Muilla leaves do not smell like onion/garlic

At Edgewood

  • Found in serpentine and non-serpentine grasslands
  • Flowers March – April
