The Informal Garden at Jackson's Mill is located behind Calhoun Cottage and the Director's Cottage.
The garden was designed by WVU Extension landscape architect T.D. Gray and has a wheel-spoke plan with rough dimensions of 60’x60’. A circular rough-cut stone fish pond is located at the center of the garden and dates to at least 1934. The Informal Garden is a common setting for meditation programs at camp. Adjacent to the Informal Garden is the All-Star Rose Garden, which was moved from another area to the Informal Garden in the 1980s. The rose garden is contained by a high white picket fence with a large white wooden star. A white picket fence was built around the rose garden in 2001 to protect it from deer. This rose garden was renovated in 2019.
