Thyme is a tricky herb to identify because it comes in so many different varieties. However, there are a few different things you can look for that will help you identify the variety of thyme you have.
First of all, take a look at the shape and the color of the leaves. If they are gray in color and have a fuzzy texture, it’s likely that you’ve got Wooly Thyme. If they are a gray-green color and have silver edges, you’ve got Silver Thyme.
English Thyme has deep-green leaves that are slightly glossy. It also grows in large, circular mounds and will be covered with small, lavender-colored flowers during the summer. This makes it one of the easiest varieties to identify.
Turkish Thyme has small green leaves that grow very close to the stem. During the spring, it will also be covered in small pink flowers.
