African Marigold

Tagetes erecta

The Story

Plant Bio

Tagetes erecta, the African or Aztec marigold, is an upright branching annual native to Mexico and Guatemala, growing one to four feet tall. Deeply divided, gland-dotted leaves release a strong scent when crushed, and large double flowerheads three to six inches across open in dense pompons of yellow, gold and orange from summer until the first frost.

Despite the common name this is a Mexican plant, and it is the flower carried on Dia de Muertos altars. The sap can raise a rash on sensitive skin, so wear gloves when deadheading a large planting. Grown as a whole-bed cover crop and dug in it suppresses root-knot nematodes; as a scattered border edging it will not.

Uses & Benefits:

Ornamental UsesLarge pompon heads in saturated yellow, gold and orange over a very long summer season.
Practical UsesA traditional cut and garland flower, and a nematode-suppressing cover crop when grown as a full bed and turned in.
Ecological BenefitsAttracts butterflies, though the fully double pompons hold little accessible nectar — single-flowered forms are far more use to pollinators.

Planting

How to Grow

  1. Sow after the last frost or set out transplants.
  2. Give full sun and any freely draining soil.
  3. Space plants twelve to eighteen inches apart.
  4. Water at the base, keeping the flowerheads dry.
  5. Deadhead spent heads to keep it blooming.
  6. Stake the tallest cultivars in exposed sites.

Pro Tip

Marigolds flower hardest in lean soil; rich, heavily fed ground gives you tall soft foliage and far fewer blooms.
