How to Identify Green Giants
- 1). Examine the foliage. Green Giants have dark green, flat foliage that resembles scales, according to the U.S. National Arboretum. They keep their color all winter in most climates.
- 2). Take into account the shape. Green Giants naturally have a conical shape that is consistent without requiring pruning, the U.S. National Arboretum says. If the tree you are looking at has a more jagged appearance it is probably not a Green Giant.
- 3). Watch it grow. Green Giants grow quickly, eventually reaching 60 feet tall and 30 feet in width, according to the U.S. National Arboretum. Their rapid growth is one of the Green Giant's most defining features, and one of the reasons they are so popular.
