Is Silene Armeria (sweet william catchfly) annual or perennial?

Dave's garden has it listed as both, so I'm confused. I was thinking about growing this in spring, but I'd like to know whether I'll have to save seed or take cuttings in winter or something like that. Also, if it is perennial, I'd like to know how hardy it is.
