What common name corresponds to the plant Galium odoratum?

Galium odoratum is commonly known as Sweet Woodruff. This plant is a perennial ground cover that is particularly appreciated for its fragrant foliage, which has a sweet, hay-like scent when dried. The name "Sweet Woodruff" specifically reflects its aromatic properties and is widely used in herbal lore and as an ingredient in potpourri and various culinary dishes, especially in desserts and beverages.

The association of Galium odoratum with sweetness derives from the compounds present in its leaves, which release a pleasant aroma, especially when crushed or dried. Additionally, Sweet Woodruff is often found in shady woodland areas, which further contributes to its popularity as a shade-loving ground cover in garden landscapes.

This clear connection between the botanical name and its common use helps to establish the appropriateness of "Sweet Woodruff" as the correct answer. The other common names mentioned, such as Bearberry Cotoneaster, Emerald Gaiety, and Wintergreen, refer to entirely different plants and do not relate to Galium odoratum in any way, emphasizing why Sweet Woodruff is the accurate identification for this species.
