What to Expect

Mercer Botanic Gardens offers visitors a chance to escape to a garden oasis. This outdoor treasure is spread out over 180 acres with 60 of those being maintained for the enjoyment of visitors. Here, you can find bamboo, flower displays, daylilies, endangered species, ferns, and tropical plants and trees.

A new boardwalk and ziggurat – an earthen tower – are among the improvements planned at the gardens to help them be more flood resilient. A new pond is also in the works, as is a new rookery and water feature.

The gardens are also a favorite spot for birding. They are home to many eBird hotspots and offer plenty of opportunities to view southeast Texas favorites. They are also a good place to stretch your legs and go for a walk or jog along the 2.5-mile Mercer Arboretum Loop. The park hosts a variety of events throughout the year, ranging from festivals and plant sales to educational tours, lectures, tai chi sessions, and holiday camps.


The garden was started by Thelma and Charles Mercer in the 1940s when they purchased 14.5 acres of natural land alongside Cypress Creek. Thelma, who was an avid horticulturist, did most of the initial selective clearing and planted trees like dogwoods, rusty black-haw viburnum, camellias, and more. She also established several theme gardens, such as the fern garden and daylily collection.

Six years after Hurricane Harvey, Mercer Botanic Gardens is open to visitors again, and the gardens are in excellent shape. Visitors can explore the many different ecosystems and learn about a variety of plants, including bamboo, color displays, endangered species ferns, tropicals, gingers, herbs, and more.

Located on Aldine Westfield Road, the park is divided by the road, with Precinct 3 maintaining the eastern side that includes the botanical gardens. The facility is free to visit, and you’ll find hiking trails, a butterfly house, restroom facilities, and picnic areas with 58 picnic tables, two barbecue pavilions, a boardwalk, a hickory bog, a cypress swamp, a maple collection, plus more. A must-see place!
