A black plaque with gold lettering commemorates the Rhododendron Gardens, a dream born from Robert Sutherland's vision, established in 1985. It lists the garden's history, including its association with the Horticultural Society of Amherstburg, the Chamber of Commerce, and the Royal Horticultural Society. The plaque also mentions the garden's 150-year lifespan and the inclusion of azaleas in its maintenance.
