One of the first Trilliums I have found this year (2019) is the Chattahoochee Trillium, T decipiens. It is found along the watershed of the Chattahoochee River in Georgia. While I am quite confident with this ID, as I'm not a botanist it is not verified officially.
This second Trillium is a Spotted Trillium T maculatum that I found at the Wolf Creek Trout Lily Preserve in Grady County, Georgia. Many signs in the preserve suggests that this is correct name for this trillium.
