There are a variety of plants that can be grown in your garden and serve a far greater purpose than just “looking pretty”. One of the very best is French Marigold, because it can serve several functions there. This elegant little flower is much more than just a pretty face.
French Marigold (Tagetes patula) is a very beautiful flower that also serves a valuable function in your garden. French Marigolds are a natural insecticide. They ward off aphids, beetles, and other pests that like to munch on your beautiful plants and leave them ragged and forlorn.
French Marigolds are both smaller (potentially taking up less space in your garden), and more “showy” than other varieties. This combined with the fact that they can ward of garden pests from surrounding plants is an excellent reason to add them to any garden. This goes for your flower bed, as well as vegetable gardens. Their beautiful dark green foliage allows them to blend in nicely there as well.
However, if you do add them to a vegetable garden, be aware that unlike other Marigold varieties, Tagetes patula is toxic. I say this because I do actually use some of my flowers as vegetables. Not only are some valuable medicinals that can be eaten (for example, Dandelion, which we mow down as a weed!), but they can add a bit of color and aesthetic appeal to salads and other dishes as well. Do not try this with French Marigold; however, for it is quite poisonous. This is why your garden pests tend to avoid it in the first place.
There are several plants that can serve as an attractive and useful addition to any garden project. French Marigold is perhaps one of the best choices because it saves space, adds beauty, and keeps destructive insects at bay at the same time. That is quite a list of super powers for any little flower.
