Over the last few years, artificial flowers have really started to look real. My parents have seasonal bouquets that they bring out throughout the year that absolutely look real. It's amazing how fake they look with even the smallest amount of dust on them, I guess real cut flowers don't stay around long enough to collect dust. A simple way to dust all of the petals, leaves, etc. is to use a can of compressed air. Just give the flowers a good once over every few weeks to avoid having to ever wash them.
