gosh, you’d almost never be able to afford fresh arugula and your latte would have to be made from instant coffee!!!
the HORROR
Arugula grows in most everyone’s yard and people used to have a hell of a time getting rid of it until some smart feller figured out city folks would pay good money for the danged stuff!
Beside that, one collard green plant can feed a family of six for nigh onto a year... :)
I grow my own arugula.
