What Are African Marigolds?
African marigolds (Tagetes erecta) are tall-growing annual flowers known for their large, globe-shaped blooms. Unlike French marigolds, which stay compact, African marigolds can grow 2 to 4 feet tall and produce impressive flower heads in shades of yellow, orange, and gold.
These marigolds are perfect for:
• Garden beds and borders
• Large containers
• Cut flower production
• Mass plantings for color impact
Their bold blooms make them one of the most popular flower seeds for gardeners who want strong visual results.
When to Plant African Marigold Seeds
African marigolds are warm-season flowers that grow best after the danger of frost has passed.
Outdoor Planting
Plant seeds outdoors after your last frost date when soil temperatures have warmed.
Indoor Seed Starting
For earlier blooms, start seeds indoors 4 to 6 weeks before the last frost.
Starting indoors helps plants establish earlier, leading to larger plants and earlier flowers.
