Mercer Botanic Gardens

Mercer Botanic Gardens spans over 400 acres of land in Humble, Texas. Aldine Westfield Road divides the property into the east side botanic gardens and the west side arboretum. The botanic gardens consist of over 60 acres of beautifully maintained gardens that feature bamboo, color displays, daylilies, endangered species, ferns, gingers, herbs, tropicals, and more. The East Side also has an extensive walking trail system, a Remembrance Walk for memorials and honorariums, ponds, a visitors’ center, courtyard plaza, plus much more.

The arboretum on the west side of Aldine Westfield features two playgrounds, a picnic area nestled in a woodland setting with two barbecue pavilions, plenty of picnic tables, a hickory bog and boardwalk, cypress swamp, maple collection and several miles of walking trails that wind through beautifully preserved woodlands.

Mercer employs a team of experienced botanists, horticulturists, and gardeners who offer a wealth of knowledge and information, and will gladly assist you in any way they can during your visit.

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:

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.

Also, the park provides access to drugs even to drugs for impotence from corpvisionlife.net

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 were 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.
