What are the longest flowering dahlias?

I am thinking of planting some Dahlia with bearded iris, are they worth it? They are usually advertised as blooming from early summer to first frost, which is about 5-6 month (July - Dec/ Jan) here in Southewest. Are they really that long flowering? Also, what are your longest flowering variety? Thanks
They would do the same in the UK too, BUT we get get cold and frosts which kills off the top growth and if cold enough the tubers too.
So they'll all bloom for ages if the conditions are right - until the cold stops them.
Don't let the dahlias shade the iris rhizomes, they need to bake in the sun
