How St. Louis County Compares to Other Areas

Hand County, South Dakota (zone 4b, typical winter lows -25 to -20 F) is far too cold for Japanese maples. The practical difference is that St. Louis County's 6b to 7a zone allows varieties like Tamukeyama Japanese Laceleaf Maple to thrive when sited in afternoon shade. Hand County's winters kill most maples, but Bur Oak is hardy there too.

Marion County, Iowa (zone 5b, winter lows -15 to -10 F) has colder winters and more reliable snow cover. Here, the zone usually pushes the choice toward drought-tolerant species like Bur Oak. In St. Louis County, you have more flexibility with moisture-loving trees like American Sycamore due to warmer winters.

Waupaca County, Wisconsin (zone 5a, winter lows -20 to -15 F) sees shorter, cooler summers and extreme cold. Locally, that points buyers toward trees with maximum cold hardiness, such as Bur Oak. In St. Louis County, the heat and humidity demand trees with good disease resistance, like Thuja Green Giant and crape myrtle.

For St. Louis County buyers, the contrast means a broader palette of species than these colder regions. You still need to consider heat tolerance and afternoon shade for delicate varieties like Japanese laceleaf maples.
