Heggies Rock is one of the most striking examples of granite flatrock in Georgia.  Without the support of soil, plant life has evolved over centuries to withstand the natural cycles of downpours and searing heat.  

The outcrop has a variety of habitats ranging from dry rock faces to wet seepage areas, or "dish gardens." Two endangered plants thrive in these basins: the tiny pool sprite, and the mat-forming quillwort, which grows in only one pool on the rock. The dwarf granite stonecrop, listed as threatened in Georgia, survives here, and the rare glade windflower was discovered on the preserve a few years ago.

Heggies Rock is not open to the public. Access is by arranged tours only.
