Hymenoxys grandiflora, commonly known as Graylocks Four-Nerve Daisy, is a perennial herb native to the rocky mountainous regions, subalpine meadows, and alpine tundra of the Western United States. It typically grows to a height and width of 0.5-1 feet (0.2-0.3 meters). This plant forms a low mound of narrow, lance-shaped leaves, and its bright yellow, daisy-like flowers bloom in the spring and summer, adding a splash of color to the garden. The flowers are quite showy and attract pollinators such as bees and butterflies.

Graylocks Four-Nerve Daisy is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for rock gardens, xeriscaping, and naturalized areas. It is also used in border fronts and as ground cover. This plant prefers full sun to part shade and requires well-drained soil. While it is generally low-maintenance, it can be susceptible to root rot if overwatered. It is not known for aggressive roots or significant disease problems, making it a reliable and easy-to-care-for addition to the garden.CC BY-SA 4.0
