This plant, I'm not sure it would even be considered a fern, though it resembled one, sort of, was growing in between the bricks in a court yard in New Orleans. I picked a few (not enough to be missed) because I recognized it from when I was a kid and my grandmother grew it, and I wanted some. I grew it in my court yard for years. Anyway, this plant was small, limy green, crisp and succulent and would snap off if you bent the small branches, the tiny leaves would fall off and make new plants. We called it an ammunition plant or fern. I wanted to find some more because we moved and I didn't bring any with me. Anyone recognize it from my description? Thanks
