Dandelion belongs to the Asteraceae family of composite flowers. Characterized by numerous florets arranged in a dense inflorescence that is contained by overlapping green bracts that open and close to protect the flower. The word dandelion refers to the large tooth-like indentations on the plant™s leaves and the bright yellow color of its flower head. The taproot, which can extend as much as 2 meters in depth, can be roasted in the fall and used as a substitute for coffee. Historically it was a precursor to hops used as a bittering agent in beer. The leaves are edible, though especially tasty in the spring. The milky sap of dandelions was used to purify the blood, cure stomach ailments, treat gall bladder and liver disorders.
