One of them smells like fish. One has roots thicker than your thumb that go three feet into the soil. One has been on the FDA's consumer-warning list for over thirty years.
All eleven are sitting on the catalog page of nearly every garden center in America right now and most of you have probably planted at least one of them already.
Eleven catalog lies. Eleven apothecary tales. Eleven perennials that look beautiful in the nursery pot and become a thirty-year apology in your yard. The plant at number eleven roots itself at every node it touches - pull one, the next is already anchored three feet over. The plant at number five takes over every neighboring bed within five years. The plant at number one is in every classical herbal published between 1500 and 1900 and you can buy it at the herb specialist nursery this morning.
