This program promotes horticulture across North America, encouraging people to visit gardens and other horticultural institutions.  A current membership card from the American Horticultural Society or a participating institution like the Ambler Arboretum entitles individuals to special privileges and discounts and other participating institutions.

Currently there are more than 300 participating institutions across North America and in the Caribbean. You can find a complete listing of participating institutions here:

What does this mean?

If you are already an Arboretum member in good standing, you will be receiving a membership card you can use to show to any of these 300+ gardens for free admission and other benefits. Learn how to enjoy the Reciprocal Benefits here:
