The Charles County Garden club was founded in November 1938 with two goals:

"To cultivate the spirit of good gardening in its broadest sense and to engage in civic and horticultural improvements throughout the County."

In 1943, on account of the difficulty of transportation and securing of gas, etc., the Club was disbanded until June 1947 when it was reorganized and club members abandoned the unit system. Several new committees were added in 1949 by Mrs. Frank A. Bolton, President 1949-1951: Historical, Good Cheer, Membership, Civic Projects, and Properties. The historical scrapbooks were also started in 1949.

With the exception of the war years, the Club sponsored annual Spring Flower Shows and supervised the flower exhibits at the Charles County Fair. They have also undertaken multiple Charles County beautification projects such as memorial tree plantings, preservation of natural landmarks like the 300 year old Southern Red Oak in Newburg, Maryland, assisting the beautification committees of the Charles County Commissioners, and establishing the arboretum at what is now the College of Southern Maryland. They sponsored the Maryland House & Garden Pilgrimage, designed, planned, and maintain the herb garden at Smallwood's Retreat, and helped establish a Garden Therapy Committee fpr the Women's Reformatory in Jessup to enable inmated to experience the joys of gardening.
