Aztec marigold

Tagetes minuta, commonly known as muster-John-Henry, southern marigold, or huacatay, is an annual herb in the family Asteraceae native to temperate South America (Argentina, Bolivia, Chile, Peru) and now widely naturalised across Africa, Australia, and warmer parts of the Northern Hemisphere. Plants are erect, strongly aromatic, and grow 0.5 to 2 metres tall from a fibrous root system. Stems are stiff, glabrous, ribbed, and often branched in the upper portion. Leaves are opposite below and alternate above, pinnately compound with five to seventeen lanceolate leaflets 1 to 5 centimetres long, sharply serrate, and conspicuously dotted with translucent oil glands that release a pungent, citrusy-anise scent when bruised. The inflorescence is a dense, narrow, terminal panicle of small cylindrical heads about 1 centimetre long; each capitulum bears two or three short pale yellow ray florets and three to seven yellowish disc florets enclosed by four to five fused phyllaries. Achenes are narrow, black, and topped by short scaly pappus.
