Take a stroll through the City of Oshawa's Parks greenhouse, which is dedicated to housing tropical collections and producing annual bedding plants for city parks, gardens, City Hall, the Oshawa Valley Botanical Garden, and the downtown Oshawa planters and hanging baskets. By late March, the City of Oshawa will have sown 5,000 seeds and planted 2,000 cuttings, intending to have 60,000 beautiful plants ready by May to enhance the City’s gardens and planters. The Glass Parks Horticulture greenhouse in Oshawa is one of the few remaining city-run glass greenhouses in Ontario.
