...My late father used to refer to the digoxin [heart medicine] he was taking as "foxglove," which always brought an indulgent smile to my face. Indeed it did originally come from that plant (foxglove = Digitalis pupurea), but it's a term not widely used since Thirties or maybe the Forties, and my father's the only non-gardener I ever heard refer to it by that name since I was in medical school. I'm sure Bill knows it, but he came by it honestly; others be careful, because if you acknowledge that you recognize it you are betraying your advanced age. (Or perhaps your far-flung erudition, after all. Or maybe both!)
