Weed and Wildflower Garden

The weed and wildflower garden is a collection of the many types of plants that make up the flora of Ontario. Agricultural fields, roadsides, lawns, parks, vacant lands, perimeter areas of woodlots and right of ways are some of the many areas these plants inhabit. This collection also contains some of the noxious, poisonous and invasive weeds found in Ontario.

The Weed and Wildflower Garden, University of Guelph Ridgetown Campus

The garden was initiated by Bill Allen, a former weed scientist at Ridgetown College in 1976. Maintained by Dave Bilyea from 1979 to present. Since then it has grown from 80 weeds to its present size of over 200 specimens. The weed and wildflower garden is open for public viewing from early spring until fall located south of the campus greenhouses. Visitors are encouraged to take a self-guided tour to examine the weed specimens throughout the growing season.

Obviously not every weed or wildflower in Ontario could possibly be displayed but visitors may see plants that are in their gardens or fields. Unfortunately weeds such as Giant Hogweed are not on display since it can be a health hazard. There is information available about Giant Hogweed and others on the display panels.

Which is the weed and which is the wildflower? We’ll let you decide.
