Tagetes lemmonii

Tagetes lemmonii, or Lemmon's marigold,[1] is a North American species of wild marigolds within the daisy family (Asteraceae).

It is native to the states of Sonora and Sinaloa in northwestern Mexico as well as southern Arizona in the United States.[2][3]

Description

Tagetes lemmonii is a perennial herb sometimes reaching as much as 240 cm (8 feet) tall.

Leaves are up to 12 cm (4.8 inches) long, pinnately compound into 3-5 leaflets, each leaflet narrowly lance-shaped with teeth along the edge.

The plant produces many small flower heads in a flat-topped array, each head with 3-8 ray florets and 12-30 disc florets.[3]

Taxonomic patronym

The species is named for John Gill Lemmon, husband of American botanist Sarah Plummer Lemmon.[4]

Gardening

Tagetes lemmonii blooms from fall into spring and can sometimes be blooming for up to 10 months. It can get up to 8 feet tall by across. The foliage is pungent when disturbed. The species is very drought tolerant in a Mediterranean climate and much used in California gardens where it tolerates light frosts without damage.
