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.
Researchers found that even in small dietary amounts, the lutein from marigolds had a positive effect. Marigold has also been found effective against leukemia, colon and melanoma cancer cells. Wound Healing. One of marigold's folk uses has been in the area of wound healing. Rubbed on burns, scrapes and irritated skin, marigolds provide relief. When tested on rats, researchers in Brazil found that one of the mechanisms for wound healing comes from marigolds having the ability to promote the growth of new skin tissue, as well as new blood vessels that feed the skin.
