It's important to note that "marigold" can refer to a few different species within the genus Tagetes. Some common examples include:

* Tagetes erecta (African marigold)

* Tagetes patula (French marigold)

* Tagetes tenuifolia (Signet marigold)

So, while the genus name Tagetes is the most accurate and encompassing term, specifying the species is helpful for being more precise about the type of marigold being discussed.
