How Union County Compares to Other Areas

Let's compare your climate to three different regions.

District of Columbia, District of Columbia (DC) sits in zone 7b to 8a with winter lows of 5 to 15 degrees Fahrenheit. That gap changes the local shortlist to privacy and screening options. In DC, broadleaf evergreens like hollies and camellias survive winters that would kill them in Union County. Here, you need conifers like Eastern Redcedar for year-round screening.

New Castle County, Delaware (DE) shares zone 7b with typical winter lows 5 to 10 degrees Fahrenheit. For your cart, that means spring-blooming trees like flowering dogwoods and redbuds bloom reliably there but risk flower bud damage here in late frosts. Your best bets for flowering in Union County are tough natives like Mexican Plum, which burst into bloom after the worst cold passes.

Miami-Dade County, Florida (FL) enjoys zone 10b to 11a with winter lows 35 to 45 degrees Fahrenheit. In practice, buyers here lean toward citrus, avocado, and tropical fruit trees. Those simply cannot survive your -15 degree nights. Your fruit options focus on cold-hardy types like Elberta Peach and Honeycrisp Apple, which need your chill to set fruit.

What does this mean for your Union County cart? Stick with zone 5 proven trees. Your cold winters are an asset for certain fruits and force you to choose smarter, tougher varieties for shade and privacy.
