My story of plant carnage is the one where I planted a whole mini-bog, and couldn't figure out why the plants languished and deteriorated. It wasn't until MUCH later that I found that the peat moss I used for the bog was the dreaded "Miracle Gro"-infused peat moss. I didn't even know such a thing existed! Fortunately, I only lost a couple plants, and my S. oreophila survived.
