What was the most widely used "The Language of Flowers" book during the Victorian Era?

I'm trying to learn floriography because it seems fun but I'm having trouble trying to track down the dictionary that is the most widespread one. I know that there are a lot of them there and not everyone uses the same dictionary but I want to know which book is the one that you will most likely be able to communicate with others without any misunderstandings. Or if we can't have that, then the very first version of that book that boosted it into stardom. Thanks!
