I have often wondered why on earth vendors(who ship double fans) advertise single fans, it seems there is a general daylily enthusiast rule that daylilies are a social plant(they like company when planted). I don't know if that is an actual thing or not, but I automatically shy away from single fans. It might just be a mental thing, but it seems a single fan just sits there waiting for company before it grows. Any science to that?
