Here's an experiment gone somewhat amuck. Last year I got a free packet of generic wildflowers from the Georgia DOT. It was prairie coneflowers, gaillardia and something else and I sowed them in three big buckets. I think I posted those pics in here somewhere.
They were pretty but now I have three big weedy buckets full of fire ants and a gazillion volunteers popping up everywhere. The ground around the buckets is carpeted with babies! I'll let 'em grow. At least they'll be pretty.
