Phacelia suaveolens (Sweet scented phacelia) is a native California herb in the Hydrophyllaceae family, recognized by sweet fragrance, yellow tube with purple lobes, and yellow pollen.

Sweet scented phacelia is a California native annual found in northern coastal, central Sierra Nevada foothills (Ione), San Francisco Bay, and south-central interior regions in open burns, slopes, chaparral, and closed-cone pine forest at elevations of 200 to 1,700 meters. Flowering from May to August, this aromatic plant produces lavender to purple flowers in narrowly bell-shaped corollas with yellow tube about 7 to 11 millimeters long. Growing 5 to 40 centimeters tall with ascending to erect stems that are simple or branched at the base and short-hairy, it has a delicate, open structure. Its leaves range 10 to 75 millimeters long, widely elliptic to ovate, with toothed or slightly lobed edges that contribute to its distinctive appearance. The small ovoid fruit measures 3 to 5 millimeters and contains 10 to 16 pitted seeds about 1 to 1.5 millimeters in size.
