Whistling Gardens is a 22-acre botanical garden in Wilsonville, Ontario, renowned for holding the largest public collection of peonies in North America. The grounds feature over 4,500 peony cultivars, alongside diverse perennial gardens, coniferous displays, and water features. The site was transformed from a former farm into a formal landscape by owners Darren and Wanda Heimbecker. Visitors can navigate expansive walking paths that showcase a range of garden design styles, from manicured formal beds to naturalized woodland areas. The gardens utilize a computerized fountain system that hosts synchronized water shows throughout the day. The collection is recognized by the Canadian Peony Society for its depth and horticultural significance. The park serves as both a public exhibition space and a site for extensive botanical research.
