Now, there is a plant for sale from seller Wellspring, who is one of my reliable sellers at eBay. I already ordered.

Stevia is tremendously better alternative sweetener than Aspartame, nutrasweet, saccharin and other possible cancer suspects, whose long term studies are usually sponsored by manufacturers with paid ghost writers for their reviews. I have been searching for Stevia, but the only available are seeds. Now there are plants available.

Stevia has some controversies, specifically conspiracy theories on how the sellers of artificial sweeteners have been lobbying against its approval as a natural sweetener before the US FDA.
