Have you noticed a dramatic splash of color while out on the trail? Spring and summer are the peak blooming season for the mariposa lily, a spectacular plant that is part of the lily family (Liliaceae) along with chocolate lilies and humboldt lilies. Mariposa lilies are in the genus Calochortus, which is derived from Greek and means“beautiful grass.” Although their narrow leaves do resemble grass, they are actually perennial bulbs – meaning they live for more than two years.
There are six species found in Orange County, including two rare species, Catalina mariposa lily and intermediate mariposa lily. Here are a few of the mariposa lilies that you may come across while out exploring the South Coast Wilderness.
Splendid mariposa lily (Calochortus splendens) is our most common local mariposa lily and flowers from April through early June. Look for the pale lavender-to-pink petals among openings in oak woodlands, as well as in coastal sage scrub and grassland habitats.
Catalina mariposa lily (Calochortus catalinae) is designated as a rare plant (CRPR 4.2) by the California Native Plant Society, although it is fairly common in Orange County. At first glance the white petals resemble a morning glory, but the dark centers help to distinguish these flowers. This species can be seen flowering from February through May.
Weed’s mariposa lily (Calochortus weedii) and Intermediate mariposa lily (Calochortus weedii var. intermedius) show off a variety of brillant colors, including yellows, oranges and purples. Both of these species can be seen flowering from the end of May through mid-July, although they are in bloom a bit early this year!
