Its Dutch Iris

That is what I have heard them called. I have planted them in my garden before. Don't have any now, but my snowdrops are blooming, haven't looked but should have dog-tooth violets blooming too. I had a crew clean-out my vegetable garden last year, I told them to cut down the grape arbor, but they cut down my 30 year old wisteria. It has no leaves at all, it must be done for.
