Camissoniopsis ignota, commonly known as the Evening Primrose, is a perennial herb native to the deserts of California, specifically thriving in sandy or gravelly areas such as washes and slopes. It is adapted to arid environments and is often found in the Mojave and Sonoran Deserts. This plant typically grows low to the ground and can spread to form mats. The yellow flowers, which bloom in the spring, are small but numerous, creating a bright display against the green foliage. Evening Primrose is particularly noted for its drought tolerance and ability to thrive in poor, infertile soils.

In cultivation, Camissoniopsis ignota is valued for its resilience and low maintenance, making it an excellent choice for rock gardens, xeriscaping, and other water-wise landscapes. It requires full sun exposure to flourish and prefers fast-draining sandy soils, with minimal water once established, reflecting its desert origins. While it is not commonly found in nurseries, it can be grown from seed and is a good choice for gardeners looking to create a natural desert garden. It has no significant disease or pest problems, but gardeners should be cautious not to overwater, as this can lead to root rot.CC BY-SA 4.0
