Lagophylla ramosissima, commonly known as branched hareleaf or branched lagophylla, is an annual herb native to the chaparral and coastal sage scrub of California, particularly in the western United States. It thrives in these Mediterranean-type ecosystems with hot, dry summers and mild, wet winters. The plant typically exhibits a spindly, erect growth habit with stems that can reach up to 60 centimeters in height. Its foliage is characterized by narrow, linear leaves that are often covered with fine hairs. The small, light yellow flowers of branched hareleaf are notable for their diurnal blooming pattern, opening in the evening and closing early in the morning, which is an adaptation to the pollination habits of nocturnal insects.

Branched hareleaf is valued for its drought tolerance and ability to thrive in poor, well-drained soils, making it suitable for xeriscaping and restoration projects in its native range. It requires minimal maintenance once established and can be used to add texture and subtle color to rock gardens or dry borders. While it is not commonly found in cultivation, its unique flowering behavior and resilience to arid conditions can be of interest to native plant enthusiasts. Gardeners should provide full sun and avoid overwatering to mimic the plant’s natural habitat conditions. There are no major disease or pest issues associated with Lagophylla ramosissima, but it may not compete well with more aggressive plants.CC BY-SA 4.0
