What is the difference between lemon thyme and common thyme?

Lemon thyme (Thymus citriodorus) and common thyme (Thymus vulgaris) differ primarily in their flavor and aroma. Lemon thyme has a distinct citrus scent and taste, making it popular for dishes that benefit from a fresh, lemony note. In contrast, common thyme has a more robust, earthy flavor, often used in Mediterranean cuisine. Additionally, lemon thyme typically has variegated leaves that can be green and yellow, while common thyme has small, green leaves.
