Crushed Stevia Plant

I bought a couch off craigslist, and while we were bringing it in the front door, we crushed the Stevia plant that was in one of my strawberry pots. Three of the branches survived, but about 6 snapped off...I put the branches in a container with water in the hopes that they would spring some roots, but a couples days in, most of the branches were wilting. One of them didn't look bad, so I left it in the container with water, and took one and cut it up to try rooting it in dirt.
