Hollyhock Trimming off the top

If I trim the tops of hollyhocks will I get flowers and what will happen to the plant?
Doug says - you want to trim the tops off your hollyhocks? They should be growing upwards now and then producing buds later. You don't need to prune or trim them to produce flowers.
If you prune them now, I suspect they'll develop side shoots and get so top heavy, they'll fall over. I've never pruned them, it's an interesting question so perhaps this summer I'll do it to see what happens.
My .02 is don't prune.
