I've also seen this sort of thing from fertilizer burn. Too much
chemical fertilizer next to rhizome.
Possible chemical drift from neighbors..

Or if a brand new plant, had exposure to chemical before you got it.

Never seen this without it being some sort of chemical damage.

See if later flowers open normally

It looks like a chemical damaged flower. Round up can do this sort of
damage.
