Select a two-year option when you join or renew and save! In addition, you will gain the satisfaction that your additional financial commitment is saving you and the Arboretum time and money when you do not have to renew your support each year. A two-year membership commitment also shows us that you value your experiences here and we reward that with additional 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. 


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 nearly 300 horticultural organizations across North America.  learn more

Become a Perennial Partner

As part of our member loyalty program called Member Milestones, we annually recognize those members who have been members of The Morton Arboretum for 10 or more consecutive years with no breaks in their support. We are grateful for this regular and ongoing support! These Perennial Partners celebrate each summer with a special event. In 2014, Perennial Partners with 10 to 19 years of consecutive membership enjoyed an outdoor reception and insightful program about plant production at the Arboretum. The following month, Perennial Partners with 20+ years of consecutive membership enjoyed a reception and program all about magnolias. It's just one more reason to renew your membership today!
