Do you grow marigolds in your garden? Is it because they repel some garden pests? Besides that, I love the color interspersed with my veggies (and weeds, haha!) My husband likes them in the garden because they remind him of his Grammy who used to grow them annually--and our friends who have an organic farm use them to dye their wool yarn!
These are some we picked for her to use to dye yarn with--the huge pile of flowers smelled absolutely gorgeous! :)
