WH Canon maintains and operates a 25-acre plant nursery and holding yard located in Monroe , Michigan .  From here we can efficiently stage plant and landscape material for projects of any scale.  The nursery allows the added value of stocking materials long in advance of installation to ensure availability and the best possible care and health of each specimen.  During peak season, the nursery is stocked with over one million dollars of plant and other landscaping materials.  WH Canon crews care for the more than 10,000 trees, shrubs and perennials and can transport materials all over the Mid-West.
