Although originally from Mexico, Tagetes erecta are commonly known as American or African marigolds. These showy annuals are the largest and most vibrant of all marigolds.

Description of American marigold: American marigolds can grow up to 36 inches tall, but through breeding, shorter varieties have been developed. They have large, fully double flowers in shades of yellow, gold, and orange.

How to grow American marigold: American marigolds thrive in full sun and well-draining soil, but they can also tolerate drier conditions. Plant them outdoors once the risk of frost has passed. Space seedlings 10 to 18 inches apart.

Propagating American marigold: Seeds can be sown directly in the soil. For earlier bloom, start seeds indoors 4 to 6 weeks before outdoor planting. Seeds will germinate in 5 to 7 days at temperatures of 65 to 75 degrees Fahrenheit.

Uses for American marigold: Plant taller Tagetes varieties in the center or rear of flower beds and borders, or use them as planting pockets in full sun. Create a splash of color by planting them en masse in front of shrubs or trees. You can also use them to create a small hedge around a vegetable or herb garden. American marigolds work well in containers if kept moist.

The Jubilee Series has taller varieties, reaching up to 24 inches high, and comes in primrose yellow, golden, and orange flowered varieties.
