A year or two back, I calculated - like the nerd I am - what crops can I grow that will give me the best possible ROI: return on my investment. Which plants will have the greatest impact on our household budget. 

It wasn't even close: herbs. I can buy five pounds of potatoes in the store for a buck or two. When I buy Oregano, I spend $50 a pound or so.

I've become pretty excited about herbs.

Here's a start on a reference tool for herbs. I got this from an herb site; I don't even know all of these, but here's to learning something new!
