Linanthus californicus, commonly known as Prickly Phlox or California Phlox, is a semi-deciduous perennial herb that is native to the chaparral and coastal sage scrub of California, particularly thriving on sandy or gravelly soils. It typically grows at a moderate rate to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). This plant features narrow, needle-like leaves and clusters of fragrant, tubular flowers that are white to pale yellow in color, blooming profusely in the spring and early summer. The flowers are quite showy and attract a variety of pollinators.

Prickly Phlox is valued for its drought tolerance and its ability to thrive in poor soils, making it a suitable choice for xeriscaping and native plant gardens. It is often used for border planting, rock gardens, and as a ground cover due to its spreading habit. While it prefers full sun, it can tolerate light shade and requires minimal water once established, reflecting its adaptation to dry, Mediterranean-type climates. It is not commonly afflicted by diseases or pests, but overwatering can lead to root rot. Gardeners should be aware that it may go dormant in the summer if water is scarce, re-emerging with the cooler, wetter conditions of fall.CC BY-SA 4.0
