Brad: What a fantastic set of images.
I am sure going to try to grow columbines with iris.I can grow those,Lupines,Delfs and Foxgloves dont do well for me. I already have some nice mid color perennials to go with the iris I just planted ,but there is room for a sunloving columbine.
I know there are annual poppies in the area where I just planted Mid America order.The poppies do as they please. My fear is they will be too tall for the iris. If so they will be weeded out.
