Editor's note: Named after the ancient Greek goddess of the rainbow, of course the iris is an incorrigible show-off, putting less colorful flowers to shame. And you might think that such a gorgeous flower would be difficult to grow, but they're really very easy. Just a quick PSA: irises can be poisonous to dogs and cats, so either train your fur babies to stay the heck out of the garden or plant something that won't hurt them. Or content yourself with a spectacular wallpaper from our amazing Iris collection. Take a look and we guarantee you'll fall in love!
