Green Garden is a part of Peotone Community School District 207 - U.

Green Garden Township was organized in 1853. Prior to that, it had been called Thornton, and "was included with Manhattan under the name of Carey."

Sparsely inhabited Green Garden was one of the last places in Will County to be occupied by settlers, due to its lack of timber.

On May 26, 1917, Green Garden Township was hit by a devastating cyclone. The cyclone, which appeared to have multiple tornadoes, was visible from neighboring Peotone, and left a two to three mile wide path of destruction and crop damage as it moved from west to east through Will County.

The Green Garden town hall was reduced to kindling, while the schoolhouse across the road from it remained intact. In Green Garden and Monee townships, at least 50 horses and 100 cattle were killed, and 67 structures had to be rebuilt.
