Tagetes argentina

Tagetes argentina is a South American plant species in the family Asteraceae. It is found in Argentina and Bolivia on granitic and rhyolitic soils.

Tagetes argentina is an annual herb up to 30 cm tall. The foliage is generally dense, formed of pale green leaves which are narrowly pinnately dissected. The flower heads are white, and, although each head is 5 to 6 mm across, 5 to 25 heads together form showy flat-topped clusters. These clusters are on short peduncles which barely exceed the foliage, and since many branches often bloom at once, the entire plant is generally covered in a blaze of white. Achenes directly sown after the last frost grow to flowering in 8 to 12 weeks, and continue until killing frost. The mounding form is encouraged by early pinching of the young plants. The plants tend to naturally form low mounding shrubs to 30 cm tall. The foliage is generally dense, formed of pale green leaves which are narrowly pinnately dissected.
