I actually compiled a list of summer-growing *Gladiolus a while back*, arranged taxonomically, in an effort to figure out what I could grow outside here. I could recreate it in the wiki if people think it would be useful. Also, careful using the latest version of The Plant List. I noticed that, for example, it currently recognizes about 65 more species of *Iris* in the US than are generally accepted, apparently due to an error in a source database.
