Deadheading spent booms on plants is important, especially with perennials.  

Many modern annuals have been bred so that the plant will keep blooming without deadheading. Wave petunia was the first annual where breeders managed to achieve this, but now it is rare for any type of petunias to need deadheading.  

However, this is not the case with perennials, where deadheading makes the plants bloom longer. Otherwise, many perennials will waste their energy producing seeds. After a main stem has finished flowering, cut it down to the base. Many plants will then send up a second smaller set of flower stems.  

With plants that have many flowers on one stem, pinch off individual flowers as they fade.  

With fall flowers, such as asters, you can cut off clusters of the faded flowers so that the plant can produce more.  

With plants that produce just one plume per stem, such as Shasta daisies, cut off each spent flower stem at ground level. 

With flowers that produce large numbers of tiny flowers, such as wood asters, shear off all spent blooms with shears or scissors after the main flush of flowers is spent. 

Dead flowers turn into seeds, and unless you are collecting seeds, don't allow your perennials to waste their energy producing them.
