Facts. 1  Tall marigolds are sometimes labeled African marigolds, and the dwarf kinds are often called French marigolds. 2  Tall marigolds (Tagetes erecta) grow anywhere from 15 inches to 4 feet tall with blooms that can reach up to 5 inches across.
Planting Plan. Choose a sunny location for fastest flowering; marigolds do fine in up to 20 percent shade, but take longer to bloom. Use a small garden rake to break up soil, and remove any weeds or rocks. Place seeds 6 inches apart. Cover with 1/4 inch of fine soil.
