Also known as: Hilgard's Suncup

Camissonia hilgardii, commonly known as Hilgard’s Suncup, is a perennial herb native to the arid regions of the southwestern United States, particularly found in California and Nevada. This species typically grows to a height of 12 to 24 inches, exhibiting a sprawling growth habit that allows it to adapt to its desert environment. The leaves are lanceolate and covered with fine hairs, providing a degree of drought resistance. The striking yellow flowers bloom in the spring and summer, attracting various pollinators, and are characterized by their cup-like shape, which opens in response to sunlight. The fruit is a slender capsule containing small seeds that are dispersed by wind and animals, contributing to the plant’s propagation in its native habitat.
