Herbaceous and with vigorous-growth, this herb is often considered a weed, invading certain areas of your lawn. True (wild) Dandelions, which are different from Italian dandelions, are entirely edible with verdant leaves, stems and nectar-sweet, bright-yellow flowers. During the 19th century in England, pharmacists gave wild dandelion root tea to their patients, as their greens are packed with vitamin A, C, K and E! ~8,500 Seeds/Oz.
