About plant names...

Great white trilliums are native to North America. Rich woods and thickets and mesic slopes.

Plants: A single stalk, 8-18" (20-45 cm) tall, topped by a whorl of three leaves and a single flower. A single root system can produce extensive, dense clonal colonies.

Leaves: Medium green, up to 6" (15 cm) long and 5" (12 cm) wide, oval or ovate in shape. Leaves have smooth edges.

Flowers: Flowers are up to 4" (10 cm) across, white, becoming tinged with pink as they age, and larger than other trilliums. They may be erect or tipped to one side, but they don’t hang downward. The three flower petals have wavy edges, and they are reflexed: bent backwards. Between the petals are three sepals, green, narrower than the petals, and lanceolate in shape. Flowers have six stamens, in two whorls of three, and three stigmas. Flowers are 2-3" (5-7.6 cm) above the whorl of leaves. They appear from April to May.

Fruits: Green, mealy, and moist, vaguely six-sided. They darken as they age.

Edibility: Young leaves flavor salads or soups, tasting a bit like sunflower seeds.
