Deadheading is removing old flower blooms to allow the plant to keep blooming longer. Many re-blooming plants will just get more and more untidy and stop flowering if the spent flowers are not removed. So, deadheading is a garden task that occupies a lot of time for most gardeners. Roses are one plant that needs a lot of deadheading to remove the old blooms so the plant will continue flowering.
As the flowers fade away, they begin to form seed heads. This means that the energy of the plant is being spent on the development of seeds, not more flowers. So to direct that energy to blooms, you should deadhead.

While not 100% deadheading free, wave petunias drop most of their flowers below and continue to bloom. Even though they do require a tiny bit of maintenance, their long lasting color is totally worth a bit of extra tending.
Geranium flowers are super long lasting. They grow on long stalks that just keep blooming over a long period of time. Each big flower head has masses of smaller flowers on it. When the petals have completely finished opening it is very easy to just snip off the whole stem.
