flowers

I thought they were wild but I’m told irises rarely are. Planted; invasive; European, mostly, or Asian. But there are natives, too. These, with their ribbed yellow tongues, resemble an iris called the wild flag, which grows from Nova Scotia to Sitka. How might it have come to this small valley? First a bulb, then a garden, then flowers, planted; now flowers, wild. Escapees or refugees, invaders or simply the left behind.
