From nowhere

There's celery growing in a pot. We didn't plant it. It once held thyme bought at the South Austin Farmers Market. The guy we bought that from confirmed that he has grown celery (non-bunching) and that probably some seed had fallen into the pot. It's in this way that we acquired garlic chives, now self-seeding, and two kinds of asclepias, an all-yellow variety and a yellow-and-orange variety, both of which have self-seeded. I love the aleatory.
