so i learned something today. calatheas are also called prayer plants because their leaves will stand straight up "closing the plant" at night. they don't fold like a maranta, but they do remind one of praying hands the way they stand up in the dark. so, now i know. and i have shared.
and, it further illustrates why we should know the proper names as well as the common names. i would have never known if i hadn't worked late tonight!
