Such diversity in our world.  An example is the black-eyed Susan.  They come up every year–in different spots in our yard.  They seed themselves.  They are fighting for space with other weeds.  If you look at one bed, the flowers are at different heights and even at different angles.  I love looking at them.  The flowers last a long time–weeks in fact.  They come up a little later in the season.  Every year I await them and they never fail to please me.
