Photograph of a painting of a specimen of Mariposa lily, ca.1920. The thick stems with long, curling green leaves extend from the bottom to the blossoms and buds at center. Two buds stand short on the left with four large, light purple blossoms above them. The blossoms each of three wide petals which encircle the yellow pistols and curl slightly back toward the stem. They flowers shine brilliantly on a backdrop of dark red.; "This group consists of about 60, perennial bulbs, native to the western United States. These plants are commonly known as Butterfly Lilies, Fairy Lanterns, Globe Tulips, Mariposa Lilies, Sego Lilies, and Star Tulips. Of all the species of Calochortus, Mariposa Lilies are the most attractive. The large, 3- to 4-inch, cup-shaped flowers are produced atop erect stems, 12 to 15 inches high, over a period of several weeks in late spring and early summer. The colorful, delicate blossoms consist of three, fan-shaped petals, which curve back slightly at the edges. They are marked and feathered in contrasting colors. C. albus (Fairy Lantern) has white flowers, which are sometimes stained with rose. C. luteus (Yellow Mariposa) has yellow flowers lined and speckled with rust toward the center. C. venustus (White Mariposa) may have white, yellow, red, or purple petals marked with a dark red splotch toward the center. (This variety is hardy only to zone 6) These plants are suitable for growing in containers, dry meadows, and as cut flowers." -- unknown author.
