Meadowfoam

Meadowfoam is a genus of annual plants in the family Malvaceae, native to the western United States, primarily California and Oregon. The genus contains two species, Limnanthes alba and Limnanthes douglasii, both commonly known as meadowfoam. These plants are characterized by their frothy, foam-like appearance when in bloom, a trait that gives them their common name. Meadowfoams typically grow in moist, open habitats such as grasslands, vernal pools, and the edges of woodlands.

The flowers of meadowfoam are typically white or yellow and bloom from late winter to spring. They are hermaphroditic and are pollinated by insects, particularly bees. Meadowfoam is well-adapted to its environment, often thriving in areas that experience seasonal flooding. The seeds are drought-tolerant and can remain viable in the soil for many years, germinating when conditions are favorable.

Economically, meadowfoam is of interest for its seed oil. The oil is highly stable due to the presence of long-chain fatty acids and is used in cosmetics and personal care products as a moisturizer and emollient. It is also being researched for potential industrial applications. Meadowfoam is cultivated in some regions for oil production, though it is not a major agricultural crop. The plant plays a role in supporting local pollinator populations during its blooming period.
