Lowest garden zone by state
Plant hardiness zone.
This measure has no better end. The order describes the states, it does not rank them — see the other direction.
Average coldest winter temperature over the past 15 years, expressed as a plant hardiness zone. This is the standard measure of what will survive a winter outdoors. Computed from station observations using the USDA band definitions rather than taken from the USDA map, whose data is not published for reuse — it should agree in most places, but a county spanning a mountain range varies inside itself more than one number can show.
