Daytime Options

The Morris Arboretum will put your event in a class of its own, away from the rush of modern life, against a backdrop of gorgeous gardens. A variety of indoor and outdoor settings may be rented with direct access to the rest of the gardens for you and your guests to wander and enjoy during our public hours. Free on-site parking is included. For refreshments you may choose from any of our approved caterers [link to vendor contacts], who represent a variety of cuisine styles and price ranges. Our outdoor events season runs from April through October and indoor events may be booked year-round. Dates may be booked up to six months in advance. Enjoy peaceful, natural surroundings for a memorable event!  

Birthdays, Bridal and Baby Showers 

Celebrate your milestone event surrounded by greenery in our outdoor reception tent. We offer three tiers of party: up to 50, 51 to 100 or 101 to 150 guests. The space allows flexible layout for your style and our dining tables and reception chairs are included.  

Indoor parties for up to 50 can be held in our Upper Gallery space with A/V capabilities and optional access to the McLean Room for catering set up.  

Events may be scheduled between 10 AM and 2 PM, with a two-hour minimum, based on open hours and availability. During the day the reception tent space is shared with our members and visitors, and we partition your space for visual privacy. If a private evening event sounds better for you, check out our options under Evening Events below

Planning a happy celebration of a passed loved one? The Arboretum may be an option for you to come together in the beauty of nature. Private programs may be held between 10 AM and 2 PM in the Upper Gallery with a luncheon following in the Side Tent. For daytime events, attendance is limited to fifty guests and must be invite-only. Open invitations with variable guest counts, funeral services, wakes or other somber events are not permitted. If you’d like to host a larger event, see our Evening Events options below.

Evening Options

Birthdays, anniversaries, cocktail parties with friends or a grand celebration are all wonderful when set in our beautiful gardens. For Celebrations of Life, choose one of our picturesque settings for your program and then celebrate at Out on a Limb or in the reception tent afterwards.  

Looking to host your employee or client appreciation event, a fundraiser or awards dinner? Perhaps a special company dinner or gala event? We have several options after hours to entertain your guests in a lovely garden setting and historic carriage house building.
