Well, it's not really WRONG since most people call them that buuut (hrmm hrmm, clears throat, prepares to lecture!) BOTANICALLY speaking, geraniums are in fact a hardy perennial, common name, cranesbill NOT the plants I just put out which are BOTANICALLY speaking, pelargoniums! End of lecture! Here's a link if you're really interested, otherwise just ignore me and go on calling them geraniums like most of the rest of the planet, except saddo know it alls like me!
