Texas Discovery Gardens is a non-profit butterfly house and native garden in Dallas, Texas. Opened in 1936 as the Hall of Horticulture for the Texas Centennial Exposition, the 7.5-acre campus includes the first public conservatory built in the Southwestern United States. Chartered in 1941 as a 501(c)(3) non-profit organization, Texas Discovery Gardens is the second oldest botanical institution in Texas, and the first in Dallas to offer botanical education programs for children. The Gardens now include the remodeled Rosine Smith Sammons Butterfly House and Insectarium, a year-round tropical butterfly immersion exhibit. In 2003, Texas Discovery Gardens was certified as the first 100% organic public garden in the state. Our property includes a tropical butterfly house, expansive lawns, fountains, intimate gardens, and indoor spaces. Our rental areas accommodate 25 - 700+ guests for family celebrations and business functions. Our mission: to teach effective ways to restore, conserve and preserve nature in the urban environment, with a focus on gardening organically and sustainably.
