Fritillaria agrestis, commonly known as Stinkbells, is a perennial herb native to California’s grasslands, chaparral, and open woodlands, with populations from Mendocino County and Butte County to Ventura County. It is adapted to heavy soils, especially clay, and is considered uncommon in its native range. Stinkbells feature an erect stem that can reach up to half a meter in height, with 5 to 12 long, narrow leaves primarily clustered at the base. The distinctive nodding flower, blooming in the spring, is composed of six tepals that are white with greenish to pinkish markings on the outer surface and a striking purple-brown on the inner surface. The flowers emit an unpleasant odor, which is notable among gardeners and contributes to its common name.

Stinkbells are valued for their unique, bell-shaped flowers and their ability to thrive in heavy clay soils where other plants might struggle. They are often used in naturalistic plantings and wildflower gardens to add interest with their unusual flowers and foliage. In cultivation, they require minimal maintenance once established, preferring full sun to part shade and moderate water. While not commonly found in cultivation, they can be grown from bulbs and may be suitable for rock gardens or as part of a native plant collection. Due to their odor, they are typically not used near outdoor living spaces.CC BY-SA 4.0
