MARIPOSA LILIES

  • Common Name(s): Mariposa, Mariposa Lily, Butterfly Tulip, Mariposa Tulip
  • Scientific Name: Calochortus species
  • Family: Liliaceae, Lily family
  • Plant Type: Perennial plants sprouting a bulb
  • Size: 1-3 feet high
  • Common Habitat: grasslands, slopes, chaparral

Mariposa means "butterfly" in Spanish, and the flowers of this plant do bear some resemblance to the winged insect. They are are a few inches in diameter and quite showy, having 3 wedge-shaped petals and sepals, forming a goblet- or bowl-shape. Calochortus means beautiful grass, referring to the long, grasslike leaves, which are not very noticeable and wither somewhat when the plant is blooming. These are perennials which sprout from a bulb, a food source for native people who roasted them in ovens.

The following chart gives some distinguishing characteristics of the Mariposas which are native to our mountains. Catalina, Plummer's and Yellow Mariposas are pictured on this page. Mousing-over the photos will identify which kind it is.
