Our yard is full of flowering plants and shrubs that I have planted over the years. The other day I saw a cluster of spider lilies that had popped up in the flower bed by the sidewalk. I had totally forgotten about them because they don't have leaves and only bloom in late August or early September. My grandmother used to have them and I always thought they were pretty. They are hard to find now and not cheap, but they multiply quickly so it's definitely worth it. I had even forgotten I had stuck some of the bulbs out in the bed by the mailbox when I relandscaped this spring.
