My favorite SDB is a baby blue whose tag I lost. I have a big clump of it, and every fall I plant sky blue pansies in front of it. The combination is one of my favorite sights in spring. ( Why do some of the older SDB's bloom down in the foliage? Is it because I have not kept up with dividing them?)
It's too bad more people aren't out touring gardens in early spring so they could see how lovely medians are. Years ago, I drove by a cemetery every day on the way to work. The miniature iris planted in front of the headstones were so beautiful. I finally tracked down the caretaker who put me in touch with a local man who had donated them to the cemetery. Amazingly, he had names of all of the iris, and started my collection with 20 or so different SDBs. That baby blue one is one of his, and it has moved to 5 different houses with me.
