Become a member to enjoy the best the Arboretum offers and help advance its conservation efforts.

Members receive free year-round daily admission. Each level of membership admits a different number of people. For example, an Individual-level membership admits only the named member, while a Household-level membership admits six individuals a day, including the member.

In addition to admission, members enjoy exclusive perks that include:

• Discounted add-on admission tickets for friends and family, ensuring you can bring loved ones and share the beauty of the Arboretum at a reduced rate.
• Special offers on event tickets, discounts in The Arboretum Store, and early access to Arboretum programs and classes.
• Free or discounted admission through the American Horticultural Society’s Reciprocal Garden Network to more than 360 botanical gardens across North America.

Your member benefits are also nature’s gain. By joining or renewing as a member, you are helping the Arboretum plant and protect trees for a greener, healthier, more beautiful world where people and trees thrive together.

All membership levels are tax-deductible to the fullest extent allowable by law. Consult your tax advisor.

Becoming a member is the best way to visit the Arboretum frequently. Pick the membership level that fits your admission needs, knowing children aged 3 and under can enter for free.

At any level, the two-year membership option is the best value when you join or renew. Two-year members receive $10 savings on their membership, invitations to exclusive member events, free Acorn Express tram tour vouchers, and a gift voucher that can be redeemed in The Arboretum Store.

To renew your membership online, you will need both your membership number (found on your membership card) and the last name of the primary cardholder on your membership account. Sign in to the portal, click the “renew” button, and follow the prompts.

You may also purchase a gift membership on-site by visiting the Member Services Desk in the Arboretum’s Visitor Center, or by calling the Membership Hotline at 630-719-2453, which is available daily from 10:00 a.m. to 3:00 p.m.

Membership at The Morton Arboretum includes reciprocal admission to gardens that are part of the American Horticultural Society’s Reciprocal Garden Network. The Reciprocal Garden Network allows members of public gardens to visit other participating gardens free of charge.

Those who are members of participating public gardens and who have one name on their membership cards are eligible to be reimbursed for up to two general admission tickets each time they visit The Morton Arboretum (for one member and one other person). Those with two or more names on their membership cards for other public gardens will be reimbursed only for those named on the card. Reciprocal benefits do not extend to special event tickets.

To receive the benefit, purchase general admission tickets in advance online and then bring your receipt and membership card or other membership identification to the Visitor Services desk in the Visitor Center between 9:00 a.m. and 4:00 p.m. for a refund. If you have questions, please email tickets@mortonarb.org or call 630-725-2066 between 10:00 a.m. and 3:00 p.m. Check to see if your garden membership is part of the program.

Please note that The Morton Arboretum does not honor reciprocal admission for members of gardens with 90 miles, other than the Chicago Botanic Garden.
