Nice to hear i am not alone! I am hoping for a nice long flowering season for the plants in question, but that largely depends on the weather i think.
I am also hoping that some of the early stuff like oriental poppies and hardy gerainiums (of which i have loads) will put on a second show later on. They are nearly over already (at least the poppies are) and i shall be cutingthem back once they are finished in the hope of regrowth and reflowering towards the end of the summer. I havent suceeded in getting them to do it yet but there is always a first time!
Another 'saver' I have up my slieve is homegrown bedding plants. The last couple of years I have left it late to plant these out and as a result the flowering is later. More by chance than by judgement i might add ;D. This year I hope this might be a way of extending the flowering season, boosting (possibly flagging) perennial displays.
