About TEXAS DISCOVERY GARDENS

Texas Discovery Gardens is a 501(c)(3) nonprofit public garden and environmental education organization located in Fair Park, Dallas. The 7.5-acre site includes the Rosine Smith Sammons two-story Butterfly House & Insectarium, native plant gardens, a greenhouse, a Snake & Reptile indoor exhibit, garden trains and outdoor play and learning spaces. The organization operates year-round education and public programming (EarthKeepers® school programs, summer camps, homeschool days, plant sales, volunteer opportunities and community events) and is partially supported by the City of Dallas. In recent filings the organization reported program-driven revenue and maintained significant program activity (most recent fiscal-year reporting shows revenue and expense activity consistent with an active, operating museum/garden organization). Texas Discovery Gardens emphasizes organic, sustainable horticulture (stating it is the first public garden in Texas certified 100% organic), hands-on science and conservation education aligned with school standards, and community access to urban nature within Dallas' historic Fair Park.
