I'm fairly certain that an anemone is a sea flower-thing. I doubt that that's what the artist means. Or i dunno, he/she's using translation software and i shouldn't try to read too much into it.

Fressure does not exists in french as a verb.
I think it might be used by butchers to designate some piece of meat but ...
That would not be quite as poetic.

Also anémone designate both a flower-like sea animal and an actually flower.
