Did you know the leaves of marigolds have been used to remove warts?
I plant marigolds to help keep bugs out of my garden.
Marigolds are grown and harvested in Mexico to be added to chicken feed. Chickens eating marigold-enriched feed produce eggs with a deep yellow color.
Marigold blossoms themselves are quite edible for humans, too, and are often used in egg and cheese dishes.
The blossoms can make a yellow dye for fabric.
