One of our common but little known garden weeds turns out to be related to spinach and equally nutritious! It's called lamb's quarter and it grows in the warm season when spinach is gasping for air, making it an admirable substitute. The mineral rich leaves, roots and seeds of lamb's quarter are all edible, but most folks just harvest the tasty young leaves for salads, cooked greens or to blend up in their smoothie. Napoleon's troops ate it when their food stores ran low and it was a favorite salad ingredient during the great depression. We have 4" available on our herb table for those who want to introduce these readily reseeding annuals into their garden or wild space!
