Like many people, I've grown alfalfa as sprouts. But now I learn that it is the mature leaves which are used medicinally. (The sprouts are simply used as a dietary adjunct.) Has anyone grown alfalfa for the leaves - in the home garden, not as a fodder crop? When to sow the seeds? When is the best time for harvesting the leaves? What soil and climate conditions do the plants prefer? Has anyone used the leaves (not sprouts) for cooking - how? And, since info on the WWW is conflicting, is alfalfa an annual or a perennial?
