Douglas Fir Dwarf Mistletoe

Overview

Douglas Fir Dwarf Mistletoe (Arceuthobium douglasii) is an evergreen dwarf parasitic shrub plaguing Douglas Fir trees across the northern and western states of the US. This species attaches to the limbs of Douglas Fir trees and does not produce its own leaves; instead relying on the tree for nutrients and water. The small, yellow-green stems are speckled with small, greenish-yellow flowers that grow in clusters. The species produces seeds with sticky pillows that help it spread easily from tree to tree. While the plant does not pose a major threat to the tree, it does reduce its overall health and vigor and can ultimately stunt the tree's growth.
