Mistletoe is a unique evergreen plant that grows on the branches of trees and shrubs, drawing water and nutrients from its host while producing its own food through photosynthesis. It is well known for its small white berries, leathery green leaves, and its long-standing association with winter celebrations and holiday traditions. Mistletoe provides food and shelter for many birds and insects, making it an important part of woodland ecosystems. It prefers partial to full sunlight and grows best on healthy host trees. USDA Hardiness Zones 5–9, depending on the species and local climate conditions.
