My niece worked for a catering company and there were a few times she brought home beautiful fresh flower arrangements from an event simply because no one else had taken them.

When my roommate from college got married, she had artificial flowers for her bouquet, the attendants, and the table arrangements. They turned out really pretty.

I don't have a green thumb so I have a hard time keeping a bouquet of fresh flowers or a potted plant. I'd be okay with artificial flowers.
