Dandelion has followed in the footsteps of pilgrims for millenia. The genus, with over 250 species, grows all over the world. As most of us know, dandelion thrives just about anywhere. What isn’t as well known is that it improves soil quality. Roots draw minerals up from deep layers of earth – concentrating them in the whole plant. Dandelion leaves can be a gourmet green if you know when to harvest and how to prepare them. They are most delectable in the early spring before flowering.
