Membership FAQs

Trails and paths wind through The Morton Arboretum

Learn how to access your membership account online, sign up for monthly giving, take advantage of the Reciprocal Admission Program and the Member Milestones loyalty program, and know who to contact when you have questions.


Your Best Value 

Select a two-year membership option when you join or renew, and you can be assured that you have received the best value for your membership support.  As our thank-you, you'll receive additional two-year benefits that include invitations to exclusive member Enrichment Events and free Acorn Express tram tour vouchers.


Our unique Member Admission Benefit

Unlike most membership programs, we do not limit you to a specific numbers of adults or children on your membership. If you choose a membership level that allows 4 admissions, like the Morton 4 for example, that means you may bring in any combination of four people, adults or children. 


Bring additional guests

Guests are $5 each when accompanied by a member (limit of two guests per member)! Guests are admitted at this special price when arriving with the member in the member's car. If a member and guests cannot fit into a single car, then two vehicles "bumper-to-bumper" may be admitted. 


Take advantage of the monthly giving opportunity

Is my membership tax deductible?

The cost of membership to The Morton Arboretum is tax deductible to the fullest extent allowed by law. The value of benefits received is insubstantial and the cost of membership is fully deductible. Please consult your tax advisor. 


Use the Reciprocal Admission Program 

Your Morton Arboretum membership card is your passport to America's garden treasures. Receive special admission privileges in addition to possible discounts on gift shop purchases and special events at more than 300 horticultural organizations across North America.  learn more


Members always save on Special Event tickets

Members always receive the best price on tickets for our Special Events, like Easter Brunch, Craft Beer Festival, and Illumination. Purchases can be made in person, by phone, and online through the webstore. 

All members are able to use the online webstore for purchases by using their membership ID number, found on their permanent membership card (not a new-member temporary membership card).

As a new member you will be able to use the online webstore for ticket purchases after you have received your permanent membership cards by mail. This could take two to three weeks. If you have not yet received your permanent cards, please call or visit The Morton Arboretum to make ticket purchases at the member price. Our ticket line is available at 630-725-2066, and is open daily from 10:00 a.m. to 3:00 p.m.. 

Interested in buying tickets online? You will need to create a user ID and password  using your member ID number (located on your permanent membership card) for the Arboretum's online ticketing system. This is separate from the credentials you've created for your online membership portal.
