Can I have a photography session at Mercer?
Photography
We ask all photographers to please read and follow these photography guidelines while using the facility.
All professional photographers with clients must read these guidelines and sign in the binder at the Visitor Center before every photo shoot.
For more information or assistance, please contact Mercer at 713-274-4160.
Can I bring my pet to Mercer?
Just like plants are important to us, we understand that pets are an important part of many residents’ lives. Visitors are allowed to walk their dogs on the arboretum trails on the west side of Aldine Westfield. However, in Mercer’s botanic gardens on the east side of Aldine Westfield, pets are only allowed for pet portraits; owners must complete a Pet Portrait Form (PDF) and submit it to Mercer two weeks prior to the portrait sitting. Please send forms through mail, or in person to:
22306 Aldine Westfield Road
Humble, Texas 77338-1071
Pets must be on a 6-foot leash at all times and must be cleaned up after. Seeing-eye and hearing-assistance dogs are allowed throughout both the arboretum and botanic gardens.
Many of the plant collections in the botanic gardens are priceless. For their protection and your safety, please abide by the rules and regulations while visiting Mercer Botanic Gardens.
How do you read the plant labels?
Labels and interpretive signage throughout the gardens provide plant information. Display labels include the plant’s common name, Latin name (scientific name), plant family, and geographic origin. This information reveals how plants are related and suggests suitable growing conditions.
Who are Thelma and Charles Mercer?
Mercer Botanic Gardens owes its existence to Thelma and Charles Mercer, who bought 14.5 acres of wild woods alongside Cypress Creek in 1949. The only opening in the wooded land was a small burned area. Over the next 24 years, the Mercers created a garden paradise despite floods, droughts, and nature’s other familiar ravages.
What is the accessibility of the gardens?
Most garden areas are accessible to wheelchairs and strollers. Please contact the park to request special accommodations or to reserve a wheelchair.
