Selecting Wildflowers for Zone 4 Gardens
Before delving too far into wildflower selection, it’s important to understand that USDA zones are based on temperature, and not necessarily on geography. A flower that’s native in one part of zone 4 may be invasive in another part.
This is especially important to remember when planting wildflowers, as they are usually self-seeding (and more likely to spread) and because they are often meant to be low maintenance and able to survive in their native environment with very little intervention.
You should check with your local extension office to learn more about native wildflowers before sowing any seeds. With that disclaimer, here are some zone 4 wildflower varieties that ought to thrive in your zone.
