Are marigolds perennial or annual?

Common garden marigolds (*Tagetes patula* French marigolds and *Tagetes erecta* African marigolds) are frost-tender perennials native to Mexico and Central America. In USDA zones 9–11, they can survive as short-lived perennials or reseed reliably. In zones 3–8 — the vast majority

Marigolds are sold as annuals at every garden center in the United States, and for the vast majority of American gardeners, that's the correct way to think about them. Plant them in May, enjoy them through October, and pull them when frost hits. But the full picture is more nuanced, and understanding it helps you get more flowers with less money.

The technical answer: tender perennials vs. true annuals

Per University of Florida IFAS Extension, marigolds are native to warm regions of Mexico and Central America, where they grow as perennials in their native habitat. Tagetes erecta and Tagetes patula complete their life cycle in one season in temperate gardens — which is the definition of annual behavior — but they are not true botanical annuals that die after a single seed-to-seed cycle by genetics. They die because of frost.

This distinction matters practically. In zone 9 and warmer, a marigold that escapes frost can keep growing into its second and even third year.
