Oh Daniel I feel for ya--there are not many plants that tolerate the heavy wet sticky stuff part of the year and dried out brick soil the rest of the year. Here we have alkaline silt/clay loam and it's a challenge too. We don't generally have a long wet season though, just a couple of weeks when the snow melts.
And, I also have a garden full of stuff that helps me forget that I'm in UT
Here's a couple links for ideas of 'waterwise' plants for clay soil and tips
