Use fresh greenery anywhere it won't dry out or make too much mess and faux greenery for hot spots like the fireplace mantle or over a kitchen window. For example, we live in a cold climate so I use fresh garlands and wreaths on our front porch. When it's -20ºC outside it actually freeze-dries the greenery and preserves it so that it will last all season with no misting or maintenance required. If you lived somewhere hot, faux might be a better option for your front porch!
