Schreiner's is just 10 miles from my house. I recently attended a private event at one of the Schreiner family homes. The display gardens and surrounding fields are amazing!!!
Here are some pics from the display gardens. Every iris they offer is planted in the display gardens, and labeled with the 2013 cost of a rhizome. It really is incredible. They interplant many other perennials (columbine, thalictrum, lupine, and eremerus) that bloom at the same time, so the color is just amazing.
I loved the incredible height of these eremerus between the irises:
