Mercer Arboretum and Botanical Gardens

Named after Thelma and Charles Mercer, Humble’s Mercer Arboretum and Botanical Gardens entices visitors daily with free admission and 250 acres of land along Cypress Creek.

Although 14.5 acres of the land originally belonged to the Mercers—who used it for their home and garden—the area has since been purchased by Harris County and expanded to include several well-maintained hike trails, a butterfly house, restroom facilities and picnic areas.

The nationally-recognized arboretum and botanical garden boasts the largest collection of native and cultivated plants in the region. Among the many highlights are native Dogwood trees, vibrant pink camellias, rare camphor daisies and orchid trees. Pack a picnic and spend the afternoon spotting colorful Pine Warblers, Black-capped Chikadees and Cardinals as they flit overhead.
