Yes, I've seen those flower pictures, and received one when I retired. I thought I had a photo of it but don't seem to have it on my computer. But yes, I like them too.
The best recent book I've read, and it was loaned to me by a friend so I don't have any more about it than the title, but it's "The Secret Language of Flowers" by Shane Connelly. Seems it has more words in the title, but I think you could find it just using this title and the author's name.
Another one that was good as well was Peter Loewer's "Loves Me, Loves Me Not: The Hidden Language of Flowers." Both are interesting.
Hope you find them and enjoy. I'm sure there are others, but I am familiar with these two.
Thanks for reading the article.
It's always nice to hear from you.
