Well, considering I just turned into HD a maple tree, 5 roses, and a butterfly bush all from last year that didn't survive the winter, something as delicate as a Peruvian lily sure as heck won't survive the winter! I did pretty good, though.. only lost 3 trees to the winter this year versus a few years ago when I lost 10. But a crabapple, Hot Wings Maple, Golden Chain, 2 Autumn Purple ashes, Flame Amur maple, and Accolade Elm survived (the elm is now dead.. dog dug it up and it baked all day in the sun, which killed the roots. didn't know that Waffles had dug it up as the dogs in the morning are DH's responsibility). I wish I had invasive beauties like that!!! Heck, even my creeping phlox isn't invasive. Only thing that's invasive is grass & thistles. LOL!!
