Mystery Flower and Greenhouse Update

So today I wanted to ask for help identifying a mystery flower that has taken over one of our planters. As you can see the flowers are small Iris like in at least three colors. My wife loves them and we would like to plant it next year. Any ideas would be appreciated.
But the weather forecast is for lows in the high 30's so my wife wanted the more delicate plants, pineapple, orange and grapefruit in the greenhouse right now. I haven't finished any shelving so the plants are just hanging out on the floor.
