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,^[1] 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.
