Calylophus berlandieri, commonly known as Berlandier’s Sundrops, is an evergreen perennial subshrub or herb native to open grasslands, rocky hillsides, and prairies in the South-Central USA and Northern Mexico. It typically grows to a height of 1 foot (0.3 meters) and a width of 2-3 feet (0.6-0.9 meters). This plant forms a low, bushy mound of narrow, lance-shaped leaves, and its bright yellow, cup-shaped flowers bloom profusely from late spring to early fall, adding a splash of color to the garden.

Berlandier’s Sundrops is valued for its drought tolerance and long flowering season, making it an excellent choice for xeriscaping, rock gardens, and border fronts. It is also used to attract pollinators such as bees and butterflies. In cultivation, it thrives in full sun to part shade and prefers well-drained soils. While it is low-maintenance, it can be susceptible to root rot if overwatered. It is not known for aggressive roots or significant disease problems.CC BY-SA 4.0
