For a relaxed, quiet activity, consider going to the Orchid Society, located right next to the Morikami Museum. They have greenhouses and open gardens with many different types of orchids, as well as a gift shop. It is also a great location to have events, as you can host a wedding or other type of event outdoors or inside their beautiful greenhouse. There is an attached kitchen but you would have to rent or bring your own tables and dinnerware, and hire a caterer or bring food.
Admission is $8, Hours: Tuesday - Sunday, 10:00am - 4:30pm
Directions: 4 miles west of I-95 on Linton Avenue, then south 3/4 mile on Jog Road
