deadheading flowers

Should I cut dead flowers off irises and sombrero coneflowers? Is cutting of the flower for looks, to make it bloom more, or to stop them from reseeding? Should I just cut flower off or cut the whole stem to the ground? If they don’t reseed, does that mean they won’t come back next year even though they are perennial?

Thank you very much.

if you cut off the spent flowers of the Iris it helps strengthen the whole plant by not having to use all of their energy on making seed….many flowering plants need deadheading…it usually will not stop the flowers blooming next year…..b
