I came across a situation where I wanted to use a phrase like "flowery language" or "flowery speech", I looked it up and found 美{び}辞{じ} online.

I did a little research:
Initially I looked for the root in another dictionary. I found 美{び}辞{じ}麗{れい}句{く}. I asked a Japanese friend and they said they had never heard of this word nor the first part of the word.
I also searched another dictionary and came back with 美{び}文{ぶん} and 華{か}言{げん} as viable options. I'm not sure about 美文 but with 華言 that same friend they had seen or used it before.
Which would be the best way to convey "flowery speech/language" while not becoming to complex for everyday conversation or business talk?
