On my forever quest to find healthy alternatives to refined sugar for the family and for my guests, I have definitely found one that I have fallen in love with over the past couple years after I grew it in my herb garden for the first time in 2011. The name of the plant is Stevia, and it is very likely you have heard of it before since it is mentioned in commercials for a product called Truvia. I am not recommending Truvia in any way. I have not used it. I have since purchased stevia packaged by Trader Joe's, and am pleased with the product, however, there is nothing like growing it in your own yard.
I have started to grow it in my butterfly garden section of my yard instead of the herb garden with even better results.
One very cool way to sweeten coffee calorie free is to add the dried leaves to the coffee beans in the grinder, or the crushed leaves to your coffee grounds. Same goes for tea. While I know it can be purchased in highly processed form from the grocery store under the name Truvia, I am always hesitant when something is processed to the point of unrecognizable. I still have dried leaves, and have ordered the plants from Michigan Bulb and purchased from our favorite local nursery, Schwartz's Greenhouse.
