I have always loved spider lilies (Lycoris radiata) but don't have much luck in growing them. They are everywhere in early autumn, growing along roadsides, next to ditches, in meadows. But they are somewhat temperamental, from what I've read. They don't like to be disturbed, and make take more than one season to bloom once planted.
Anyway, they must grow quickly, because I discovered two in my back yard, only when they were about to bloom. They are so fascinating and are a harbinger of cool weather. I really love these plants.
