The Gardens at Washington Park are located in Sandusky, Ohio. They're a nice place to visit if you happen to be in that part of Ohio (the amusement park, Cedar Point is nearby). Although it's not big, there are some very pretty flower displays. Visitors can see a sunken garden, a greenhouse displaying tropical plants, and the well-known floral clock that even spells out the date.
The garden is open year-round from dawn to dusk. Admission is free.
