On July 26th, I plucked all the basil leaves off this stem when I made some pesto.  The next day, I put the stem into a bottle of water and a week later it grew roots.

Today, i checked it again and it had a ton of roots and some bigger leaves in addition to some new ones budding.  So, I gave it a new home in a self-watering pot that I bought yesterday at Home Depot.  Let’s see how long it lasts.
