I am growing stevia. Today I stopped by my local grocery store and they had a stevia plant out in front so I grabbed it. I wanted to do it last year, but I didn't get around to it, so consider 2012 the great stevia growing year!
Obviously I need to get some compost for this. After I left the store I tasted a leaf and WOAH, was it sweet! My plan is to throw a few leaves in my summer smoothies and then dry them out at the end of the summer and hopefully use them in the winter in the same way.
