Garden Etiquette
Mercer's plant collections are priceless, like art in museums. For their protection and your safety, please abide by the rules and regulations while visiting the gardens.

  • Please admire the plants, flowers, fruits, and labels, but do not remove anything from the gardens.
  • Artists and photographers are welcome, but please check in at the front office and do not block paths or step in garden beds.
  • Please stay on marked paths and designated nature trails.
  • Seeing-eye and hearing-assistance dogs are allowed throughout the park. All other pets on leashes may visit the west side only.
  • Jogging, in-line skating, and exercising are allowed on the west side of the park. Bicycles are allowed on the asphalt roads of the west side. Swimming and team sports are not permitted at Mercer.
  • Please help keep Mercer clean and safe by using trash receptacles and designated picnic areas.
  • Fires are allowed in the barbecue pits on the west side only. Overnight camping is not available.
  • Alcoholic beverages are not allowed.
  • Glass containers, balloons, and pinatas are not allowed, as they can be harmful to park patrons and wildlife.
  • Children under the age 15 must be supervised at all times.
  • Although no food services are available at Mercer, there are many local restaurants in the area. No picnicing in botanic gardens.
  • The animals in the park are wild and should not be approached. They are also part of nature and should not be harmed or harassed. If you see an animal acting strangely or in a situation that puts people or the creature at risk, please contact park personnel immediately.
