What does Mariposa lily look like?
Mariposa lilies grow from bulbs and send up slender stems that can reach over 30 centimeters tall. Their flowers vary in form: some are open with wedge-shaped petals, others are rounded or pointed. Each flower has six parts called tepals, arranged in two sets, with the inner ones often larger and brightly marked. The inside of the petals is often covered in fine hairs, and the blooms appear in a range of colors including white, yellow, pink, red, orange, and purple.
Where does Mariposa lily come from?
Calochortus is native to a broad region stretching from southwestern Canada through the western United States and into Mexico and Guatemala. The genus was first described in 1814, based on a specimen collected during the Lewis and Clark expedition. Over time, botanists have divided the group into sections based on flower form, chromosome numbers, and habitat. Many species are found only in California, and some are adapted to grow on serpentine soils.
When and how Mariposa lily blooms
These lilies bloom in spring or early summer, sending up flowering stems from underground bulbs. They grow in open places with partial shade, at various elevations. Different species prefer different habitats, such as dry grasslands, meadows, woodlands, or forests. Gardeners sometimes grow them in rock gardens or containers, especially where dry summer dormancy is needed.
How Mariposa lily is used
Native American peoples gathered the bulbs for food, eating them raw or cooked, and sometimes used the young flower buds. The bulbs were also a food source for Mormon settlers during times of crop failure. Some groups used the plant in ceremonies or for traditional medicine. Today, mariposa lilies are grown for their attractive flowers in gardens and naturalized landscapes.
Kinds of Mariposa lily
The genus includes about 70 species, with notable groups like mariposas, globe lilies, fairy lanterns, cat's ears, and star tulips. Each group has its own flower shape and preferred habitat. Botanists have divided Calochortus into several sections based on geography and genetics, with many species found only in certain regions, especially California.
What Mariposa lily means
Calochortus has played a role in the diets and traditions of Native American peoples, who sometimes called it 'sego.' The plant is also remembered for its importance as a famine food for Mormon pioneers. Its diversity and beauty have made it a subject of botanical study, especially in California, where many species are unique to the state.
