Id like to verify 2 possible varieties of lettuce. Woodland and Canada. And compare to wild lettuce unless it is the same. They are so close in looks this time of year. I've read to harvest at first buds. But would that be the milky sap or leaves? Can they be tinctured for sedative properties? Can they be combined together for the sap and laves? What is the best use from? I read tea is most common use but what part and is that fresh? Should they be dried to use at a later time? Im very new to these lettuce varieties so any help is very appreciated!
