Just cruise around the forums, see what catches your eye. Not sure there is anything really unique or innovative, we are all just fellow gardeners from around the world sharing our love of gardening and the database if full of member submitted plant photos. And it all depends what your zone is, what your general style is, how much time and effort you want to put into maintenance of plants, otherwise we can't really make suggestions if we don't have any extra info.
(On an off note, why the generic stock photo for an avatar?)
