Pansies and impatiens. So - now what happens? The pansies continue to bloom - the impatiens continue to grow - at what point are the pansies going to stop?

I mean - if I keep deadheading the panies, will they continue to bloom? They are getting a little leggy - but everything is planted so close together it's hard to tell. If I just cut the pansies back, will they rebloom in the fall? are pansies perennial?

Some have suggested that I start pansy seeds now and plant for a fall bloom - but that assumes that the current pansies will die over the summer. I am confused. Meanwhile, the impatiens are getting bigger everyday and the contrast between the pastel pansies and the neol impatiens is . . . well, unintentional.
