Giardini Mercer

Founded by Thelma and Charles Mercer and preserved as a Harris County Park in 1974, Mercer Arboretum & Botanic Gardens is a tranquil 393-acre oasis nestled in the bustling city of Humble. This serene space is divided by Aldine Westfield Road, with the east side showcasing 60 acres of themed gardens and a diverse array of plants, including color displays, daylilies, endangered species, ferns, gingers, herbs, tropicals, and more. The west side Arboretum features miles of scenic trails, the Jake Roberts Maple Collection, and natural formations like the Bald Cypress Swamp, Oxbow, and Hickory Bog. Our dedicated team of botanists, horticulturalists, and gardeners are passionate about sharing their expertise. We invite you to explore our botanical treasure and experience the beauty of nature. Mercer Arboretum & Botanic Gardens is committed to serving the public, horticultural industry, and scientific community by providing a versatile botanical resource for the greater Houston and Gulf Coast region.
