Arrowweed (Pluchea sericea)

General: Arrowweed (Pluchea sericea) is an upright shrub often growing 7-9 feet tall with several long, straight, stiff stems per plant. The stems branch towards the tips, providing a straight, stiff shaft suitable for making arrows and spears. The 2-inch leaves are lanceolate and crowed towards the ends of the stems at the top of the plant. Pink to purple composite flowers bloom in the spring and early summer.

Arrowweed is a common component of streamside communities and often forms dense thickets along streams and in washes and canyons in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) life zones.
