Lepidium fremontii, commonly known as Desert Pepperweed, is a perennial herb that is native to arid regions in the southwestern United States, particularly in the Mojave and Sonoran Deserts. It is adapted to survive in harsh desert environments, often found on sandy desert flats, rocky slopes, and in washes where occasional water runoff occurs. Desert Pepperweed typically grows up to 3 feet tall and has a bushy growth habit. It produces dense racemes of small, white flowers with spoon-shaped petals during the spring and early summer months. The flowers are not particularly showy but are attractive to a variety of desert pollinators.

Desert Pepperweed is valued for its drought tolerance and ability to thrive in poor, sandy soils with minimal water requirements, making it suitable for xeriscaping and desert gardens. It is also used for habitat restoration projects within its native range. In cultivation, it requires full sun exposure and well-drained soils. While it is not commonly used in ornamental horticulture, its resilience and low maintenance make it an interesting choice for naturalistic plantings. It is not known to have significant disease or pest problems, but its habitat preferences should be considered to avoid overwatering and root rot.CC BY-SA 4.0
