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.
Marigolds are the most sacrosanct flower of ancient India, being used to create sacred garlands for holy statues. The marigold flowers follow the sun, much like sunflowers do. The plant's blossoms can be yellow, red, orange, gold, cream or bicolored. They sit atop a tall, feathery stem with pinnated dark green leaves. Marigolds can grow to 36 inches tall and spread to 18 inches, which makes them a nice plant for the back of a flowerbed. Dwarf varieties can provide a colorful addition to the foreground of a border.
