Which species is recognized by the name Tagetes?

Tagetes is the genus name commonly associated with marigolds, which are popular ornamental annuals known for their vibrant flowers and beneficial qualities in the garden. They are often recognized for their distinctive yellow, orange, or red blooms and their ability to deter certain pests, making them a favorite among gardeners.

The marigold is commonly used in landscaping and as a companion plant due to its natural pest-repelling qualities. There are several species within this genus, including Tagetes erecta (African marigold) and Tagetes patula (French marigold), both of which are widely cultivated.

The other options represent different genera or species that do not align with the name Tagetes. Petunia x hybrida refers to petunias, which are from a different genus. Vinca is known for its periwinkle flowers under the genus Vinca, and sweet potato vine pertains to Ipomoea batatas, another unrelated species. Each of these options serves different horticultural purposes and lacks the characteristic traits associated with marigolds in the Tagetes genus.
