Not at all - ornamental hot peppers have dual use - culinary (most are very, very hot - they are great to dry when they turn red and grind them into hot pepper flakes, use in stir fry dishes etc - they tend to be smaller), but they are striking and lovely so are nice additions to interplant with flowers...or, if you are like me, just plant dozens and dozens in pots and put them in the driveway to enjoy!
Check out the ones in this thread - I am playing around with many colorful but edible hot peppers
