unusual rudbekia with tiny flowers what is it?

Sorry Alistair, on the other site it doesn't say feet high. I will go back in and put a pic on your question, but could it be helenium autumn lollipop.

i buy so many plants every year that i just forget about stuff ive planted expecting them to just pop up again months later ..i keep thinking that i will find them soon and i will have to inform everyone ive contacted to my embarrassment that ive found them but it was a defiantly a rudbekia and it stood out because it had such tiny flowers on tall stems not like the h. lolipop you suggested but miniature fully formed brownish flowers im sure i kept this big laminated label with the plants name on it somewhere ............oh well!!
