Clematis would be a great flowering plant (perennial) but if you live in Michigan you will have to wait until next Spring/Early Summer to plant it.
Morning Glories (Annuals) are gorgeous and a fast flowering plant, but again, you will have to wait until Spring.
Both plants love to climb so they should be supported by a trellis.
There are so many options.
Check out Gurneys.com and view all of their perennials and get some ideas.
This is a great site and all of their plants are guaranteed.
You could plant some tulip, daffadil and other bulbs right now and have some flowering plants in the Spring.
Have Fun !!!
