Wrap it up, people. :-) I just Googled and the original question
(punctuation reproduced intact) was "Are mint plants edible." Possibly
a troll, as there have been no follow-ups from the OP. A "mint plant"
sold or passed along as a "mint plant" presumably means one of the
common varieties of peppermint or spearmint, not every single member
of the Mentha family and related plants. The correct answer is, of
course, yes. :-)
