I planted the last of my intentionally moved iris yesterday. Some of these irises have resided now at 5 locations. Every time I move a big garden of iris, I lose some. I have 300 cultivars listed in my database but probably have lost 1/3 of them. We shall see.
Next spring when iris are in bloom, I will take a few more surveys of the old iris grounds, dig any that are special or perhaps missing, and relocate them. Then I will open it all up to iris society folks and neighbors to come and dig whatever they want.
