Becoming a member of The Morton Arboretum offers many benefits in addition to supporting its nonprofit mission.

Members enter free every day, including during special member-only hours.

Different levels of membership admit different numbers of people. For example, a Morton 1-level membership admits only the member, while a Morton 4-level membership admits four individuals a day, including the member.

For additional friends and family who visit with them, members may purchase up to two $5 discounted add-on admission tickets per day beyond their admission benefit. The discounted $5 add-on admission tickets and additional full-priced general admission tickets, may be purchased online or at the gatehouse upon arriving. They must be purchased by the member.

Members also get special opportunities and discounts in The Arboretum Store, when buying event tickets, and when registering for classes. Join today.

Because The Morton Arboretum is a member of the American Horticultural Society’s Reciprocal Garden Network, Arboretum members enjoy free or discounted admission and other privileges at more than 360 botanical gardens and horticultural organizations across North America.

The two-year membership option when you join or renew is the best value. Two-year members receive $10 savings, invitations to exclusive member Enrichment Events, free Acorn Express tram tour vouchers, and a  gift voucher that may 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.

To purchase a gift membership online, select a membership level for your gift recipient. Then follow the prompts and complete your transaction. 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.
