The first year we had a garden we planted, among other things, some collard greens. I don't even remember the variety, since this was back in the days before any sort of record keeping; although I'm pretty sure the seed packet is filed away somewhere, still more than half full (I keep old seeds around and try to start them every once and a while on an experimental basis—but that's a topic for another day). Anyways, those collards grew well enough, and, as collards do, they went to seed; and in the way of things many of those seeds were scattered all over the garden. The next spring, well before it was time to sow seeds outside, I noticed dozens of little collard plants springing up all over, and happily welcomed their presence. Here was the garden well-started, and we didn't even have to do any work!
