Ornamental berries are sources of color for the fall and winter landscape. As the leaves of deciduous trees and shrubs drop, certain plants will reveal clusters of brightly-colored berries. Some evergreen plants produce ornamental berries during the fall months. Many of these berries will stay on the plants long into winter, which adds seasonal interest throughout the colder months. Ornamental berries come in a variety of colors: black, white, purple, blue, red and orange. Hollies, pyracantha and nandina are great for color in the landscape and in holiday decorations.
