Updated July 30, 20261 min readCited sources

Marigold is a common name for several flowering plants, most often species in the genus Tagetes in the family Asteraceae. The name also applies to unrelated plants such as Calendula officinalis, the pot marigold.

What it is

Marigold most commonly refers to species in the genus Tagetes, which includes about 49 to 50 species in the daisy family (Asteraceae). These plants are native to the Americas, especially Mexico, Central America, and South America. The term also covers Calendula officinalis (pot marigold), which is unrelated to Tagetes.

Key details

Tagetes marigolds are flowering herbs with bright, daisy-like blooms in yellow, orange, or red tones. They typically grow 1 to 4 feet tall and may be annuals or short-lived perennials depending on species and conditions. They are widely grown as ornamental bedding plants and are valued for their strong scent, which is associated with pest-repellent properties in gardens.

Why it matters

Marigolds are popular in Canadian gardens as easy-care annuals that bloom reliably in sunny sites. They are also used in companion planting and integrated pest management. Some species have edible flowers and are used in food coloring, dyes, and traditional decorative practices.

In short

  • Marigold most often refers to Tagetes species in the daisy family.
  • Native to the Americas, especially Mexico and Central America.
  • Widely grown as ornamental annuals in Canadian gardens.
  • Also used in companion planting and pest management.
Canadian angle
