Common Buckthorn is a very invasive alien plant, originally from Europe. It can grow up to about 20 feet tall. Please help to slow the spread of this plant by pulling it up whenever you see it. However, please be sure that you're pulling up the right plant, as it can resemble native Dogwoods. The thorns are wicked - watch out for them!
