I recently came into a lot of Dept 56 pieces. Very excited for my village but I’m new to this. Many pieces, including the picture, have a bulb in the piece with a cord with a male plug on the other end. What does the male plug plug into for power? The second picture is a battery pack but it also only has an outgoing male cord, and the little metal female receptor seems to be for incoming power only. Sorry for not using right terms—any help much appreciated.

Is this pennyroyal or a variety of edible mint?
