What a fantastic collection of hardy mums you have, Frank! Centerpiece and Venus are so pretty! Love their colors!
I also have a problem with my hardy mums flopping and sprawling like LorettaNJ noted above. I tried to provide support but they are so heavy when bloom that the support sometime gives way. Here are some mums that are blooming right now.

Non hardy mum
I lost Volunteer and Homecoming to winter. I guess those were not as hardy as the above. I would like to try them again though because they are very pretty.
