Dwarf-Mistletoe (Arceuthobium)
Dwarf-Mistletoe Genus Details
The mistletoe is a green parasitic plant that anchors to host trees and shrubs by a number of suckers (specialized roots). They are found in the U.S., especially in the southern and western areas. In western states they are a serious problem to evergreens. Because they are a host to the parasitic mistletoe, the evergreens become weakened and susceptible to damage from insects and diseases. The plants have small rubbery leaves and transluscent berries. Mistletoe berries are considered poisonous. Flowering occurs during the spring and summer. Pollen is shed consistently by wind due to the well-exposed flowers that are usually located in the upper portions of tree canopies. As a result, pollen may be dispersed over great distances.
