The portion of Queen's Park south of Wellesley Street is maintained by the provincial government and includes the Ontario Legislative Building south of Wellesley Street, the parking lot to the south of the building, and the remaining portions of the park. In contrast to the northern portion of the Queen's Park, minimal landscaping was done to the southern portion of the park. However, the southern portion of the park includes the majority of the monuments and memorials in the park, and the Queen Elizabeth II rose gardens. The first portion of the rose gardens was dedicated in 1977, to mark the silver jubilee of Elizabeth II. An extension to the garden was added in 2003 to mark the Queen's golden jubilee. The southern portion of the park also includes the "White Trillium Garden", a garden that is landscaped with white trilliums, the official floral emblem of the province. There also exists a native species garden, a garden primarily landscaped with vegetation native to the area, including eastern white cedars, hackberries, and some perennial flowers. The southern tip of the park facing University Avenue features the statue of Sir John A. Macdonald, the first prime minister of Canada.
