Lepidium nitidum, commonly known as shining pepperweed, is an erect annual herb native to various habitats in the Pacific Northwest, including chaparral, coastal sage scrub, and valley grasslands, from Washington through Nevada and California into Baja California. It typically grows up to 16 inches tall and features a slender stem with small leaves and larger basal leaves that can reach up to 4 inches long, divided into narrow lobes. The plant produces clusters of tiny white flowers with spoon-shaped petals, which are not particularly showy but are interesting upon close inspection. These flowers give way to distinctive green to pink shiny fruits that are divided into two chambers, adding to the plant’s ornamental value.

Shining pepperweed is valued for its ability to thrive in a variety of conditions, including disturbed soils, making it a potential candidate for restoration projects and naturalized plantings. It is also used in wildflower gardens for its unique fruits and foliage. This plant prefers full sun to part shade and can tolerate a range of soil types, provided they are well-drained. It is drought-tolerant once established, requiring minimal water. While not commonly used in traditional horticulture, it can be an interesting addition to native plant gardens. Potential problems include competition with invasive species when not in its native range.CC BY-SA 4.0
