2013: Double-Flowered Giant White Trillium

On my way to the Porcupine Mountains Wilderness State Park, I stopped somewhere along M26 to enjoy the vast expanse of Giant White Trillium starting to bloom in their grandest glory. Having had the good fortune of seeing these flowers in cosmological numbers — some as big as a normal youth’s fist – for few years in a row now, I was awestruck to see this not so commonly seen variant, the Double Flowered Giant White Trillium (Trillium grandiflorum f. polymerum).

This double flower form produced occasionally by T. grandiflorum is a white six petalled flower with central ruff of small petals. Though almost invariably sterile, these are well sought after for their appearance.
