I thought so as well, but I was talking to someone about sending a funeral bouquet, and their only motivation to send one was, "What will people think if they don't see my name on something?" Eh.
Maybe I'd read a few, just to show interest and respect. But not really my thing and if would probably make me cry - I am a sensitive thing who cries easily.
No. I can't recall the last non-Jewish funeral I attended and the Jews don't do the flower thing. They bring food to the home after the funeral while the family sits shiva.
