Trillium Grandiflorum is a perennial that grows from a short rhizome and produces a single, showy white flower atop a whorl of three leaves. Flowering stems are 8-20 inches tall. A single rootstock will often form clonal colonies, which can become very large and dense. Fruits are released in the summer, containing about 16 seeds on average. These seeds are most typically dispersed by ants, which is called myrmecochory, and also by deer. Trillium grandiflorum as well as other trilliums are a favored food of white-tailed deer. The flowers have six stamens in two whorls of three, which persist after fruiting. The styles are white and very short compared to the 9–27 mm (0.35–1.06 in) anthers, which are pale yellow, but become a brighter shade when liberating pollen due to the latter's color. The ovaries are six-sided with three greenish-white stigmas that are at first weakly attached, but fuse higher up. The fruit is a green, mealy and moist orb, and is vaguely six-sided like the ovary.
