Phacelia stebbinsii is an uncommon species of phacelia known by the common name Stebbins' phacelia. The plant is endemic to California, where it is known only from a northern section of the Sierra Nevada in El Dorado County. It grows at elevations from 900-2,100 metres (3,000-6,900 ft), in forests, meadows, and on rocky slopes. Phacelia stebbinsii is an annual herb producing a mostly unbranched stem 10 to 40 centimeters tall. It is lightly hairy and sometimes glandular. The leaves are oval or lance-shaped and some have lobed edges. The hairy inflorescence is a one-sided curving or coiling cyme of bell-shaped flowers. Each flower is around half a centimeter long and white to light blue in color with protruding stamens.
