Ohio State Wildflower: Large White Trillium

Large White Trillium

The name "trillium"derives from the plant's repetitions of three. Each plant produces a whorl of three broad leaves with a three-petal blossom on a single stem. As its scientific name suggests, T. grandiflorum is the showiest of all the trilliums, with flowers measuring up to 3 inches long.  The waxy white blooms are long-lasting and tend to turn pinkish as they age. Plants can reach as high as 18 inches. T. grandiflorum is probably the most well-known trillium.
