Which plant is known for its aromatic properties and is called Sweet Woodruff?

The plant known for its aromatic properties and commonly referred to as Sweet Woodruff is Galium odoratum. This perennial herb is notable for its sweet-scented foliage, particularly when dried, which is why it has gained popularity in crafting and herbal uses. Sweet Woodruff is often used in traditional herbal remedies as well as in potpourris and as an aromatic addition to wine and desserts. Its small white flowers appear in spring and add to its ornamental appeal.

In contrast, the other choices represent different plant species that do not share the same aromatic qualities or common name. Cornus canadensis, known as Canadian dogwood or bunchberry, is a low-growing ground cover that produces red berries but lacks the sweet fragrance. Bearberry, which refers to Arctostaphylos uva-ursi, is a hardy shrub with leathery leaves and red berries, primarily valued for its ability to thrive in poor soils. Finally, Jackman Clematis is a flowering vine known for its striking blooms but does not have the aromatic properties associated with Sweet Woodruff. By understanding these distinctions, it's clear why Galium odoratum stands out as the correct answer.
