My Iris doesn’t bloom

My Iris doesn’t bloom

I live in Western Pennsylvania. My mother gave me some Iris's 5 years ago. They come up every year but do not bloom. They have multiplied & this year I only have one that is budding. Does anyone have any suggestions? They are in a location with buttercups & black eyed susans & those flowers do great. Any suggestions would be appreciated.
