Growing basil (and keeping it alive) = responsible. She will like this.
You don't have to go garden happy and buy out the Lowes garden section but pick up a plant or two next time you're at a hardware or grocery store. I'd recommend something easy like basil and/or rosemary. Grab cilantro if you're into Mexican cuisine. Freshly chopped basil, mozzarella cheese and tomatoes - perfect. Rosemary and pepper encrusted cast iron steak - even better.
...now just remember to keep the damn thing alive.
