Valeriana macrocera is a species of flowering plant in the honeysuckle family known by the common names longhorn seablush and white plectritis. It is native to California and Nevada in the western United States, where it is a common plant in mountains, valleys, open steppe, and coastal habitat types. It is an annual herb growing erect to a maximum height of 60–80 centimeters (24–31 in). The widely spaced, paired and oppositely arranged leaves are oval or somewhat oblong, smooth-edged, and up to 4.5 centimeters (1.8 in) long by 2 centimeters (0.79 in) wide. The upper ones lack petioles. The inflorescence is a dense, cylindrical, headlike cluster of flowers in shades of pale pink to white. The corolla is under a centimeter long and is divided into five lobes and a short, blunt spur.
