Dear Hivers, Garlic mustard (Alliaria petiolata) is my Photography 14 taken on June 5th. This is a HIGHLY INVASIVE species, native to parts of Europe, Asia, and Garlic mustard. It is in the mustard family (Brassicaceae).
Garlic mustard is a particularly bad weed because each plant produces thousands of seeds, which remain viable for years in the soil. The plants, being non-native, are not eaten by native herbivores (though people can eat them, and you can harvest as much as you want!). They also put out chemicals from their roots that inhibit the growth of other plants, which is called allelopathy. For all of those reasons, this is a troublesome plant, and it can invade disturbed and undisturbed natural areas. All parts of the plant are edible, but get bitter when older and need cooking because they may contain small amounts of cyanide when uncooked.
Enjoy your view;
