Grand Trillium

The flowers are generally two to three inches across, but sometimes bigger. The petals are usually pointed but occasionally rather rounded. Leaves have the same variation though most commonly pointed. Specimens vary so much in appearance from one plant to the next, & even one year to the next for the same plant, that they can sometimes be difficult to identify.All trilliums have three leaves per stem, & three petals per flower. But extremely rare specimens of T. grandiflorum produce four leaves & four petals. Such specimens were reported in An Annotated Flora of the Chicago Area (1927), by Herman Sila Pepoon (1915-1933), & these rare sports have been photographed since.
