The Early Years


The Hall of Horticulture is built for the Texas Centennial Exposition. The building includes the first public conservatory in the Southwest -- the "Garden Room" as it was called at the time, was half the conservatory’s present size. Four “Houses of the Future” are constructed on the grounds to illustrate home building and interior decoration trends. (Of the four houses, the one built by the Portland Cement Association remains on the property.)

1942 - 1945

The Garden Center served as headquarters for the War Rationing Board.

1945 - 1949

The main building served as the Women's Building during the State Fair of Texas.


The Scent Garden, one of the first permanent gardens on the site, was constructed on the northeast side of the main building.


The Main Hall was added to the building to create a space for garden club flower shows.

1960s & 70s

Renowned landscape architect Joe Lambert created the Callier Garden, Leftwich Reflecting Pool and Circular Lawn.


Grand Allee du Meadows was completed, including construction of the large fountain in the south corner of the property.


The Conservatory was renovated and the terrazzo floor in the lobby was restored to resemble its original appearance in 1936. Faerie Banton Kilgore Rose Garden was dedicated on Wed. March 14, 1990 by her son, Mr. James A. Kilgore.


The name was changed to Dallas Horticulture Center.


The first live tropical butterfly immersion exhibit in North Texas is hosted in the Conservatory during the State Fair of Texas as an annual attraction.


The Benny Simpson Texas Native Plant Collection is added to the gardens.
