Wisconsin gardens sit in the Midwest — a landscape of tallgrass prairie, oak savanna, and Great Lakes woodland. The plants below evolved with that climate (cold continental) and are hardy through zones 3–5, so once established they shrug off the local weather without fuss, fertilizer, or much water.
