florist? christian tortu

While compiling research and books for the course I will be teaching this spring, Wellness in Floral Art, I stumbled across the botanical artist Christian Tortu. The former USA White House florist, Laura Dowling, studied in his Parisian floral school L'ecole des Fleurs. He now is teaching at FlowerSchool NY and has opened studios in Asia. 

On his website he has the word FLORIST with a big ? I agree with him, the term florist has an trade-like connotation when we are really artists whom are working with botanicals, using a muse, and forming sculpture. I think the term florist is outdated and under Christian's FLORIST? he should write BOTANICAL ARTIST.  Anyone agree with me?
