If you really love to experiment,jam a galvanized nail in also,you can make a 1 cell battery
out of your plant.String plants together and you can have a garden powered led nightlight.
the copper/zinc combo makes a battery.copper positive zinc negative.

I believe that a modern cent is only 2.5% copper, the rest is zinc. However older pennies are mostly copper.
