Which plant is often associated with fragrant blooms used in gardens?

Trachelospermum jasminoides, commonly known as star jasmine, is well-known for its highly fragrant white, star-shaped flowers. This plant is frequently chosen for garden settings specifically for its aromatic quality, which can enhance the sensory experience of a garden. The scent of its blooms is a significant attraction for gardeners looking to add fragrant plants to their landscapes.

In contrast, Vinca minor, while a hardy ground cover, produces small flowers that are not typically recognized for any significant fragrance. Sarcococca hookeriana humilis, also known as sweet box, has some fragrant blooms, but its flowers are less prominent and not as widely used in the garden compared to star jasmine. Agapanthus, known for its striking blue or white flowers, offers visual appeal but lacks a significant fragrance that would lead to its association with scent in the garden.

Thus, the standout characteristic of Trachelospermum jasminoides as a fragrant bloomer makes it the most suitable answer for gardens focused on aromatic flowers.
