    While this plant is useful as a screen, it provides very few other benefits to the garden. That being said, birds do use it for perching and nesting. It is way too overplanted and will split under heavy snow or ice loads if above 10-12' tall. My rear neighbor lined his property with these when he moved in about 35 years ago. They're still around, but they look pretty haggard. If properly trimmed and maintained every couple years, a hedge of this plant can look nice without becoming an eyesore.
