Not only can the flowers we’re about to shed light on handle the harsh conditions of Wisconsin, but they’re also low maintenance and easy to care for.

2. Coral Bells
Coral bells, also known as Heucheras, are a beautiful addition to any garden. This ornamental plant blooms in the spring into bright pink or purple flowers.
This plant is native to North America, which means it thrives in arid climates. It can grow almost anywhere and doesn’t require a lot of special care.
Coral bells can spread widely, so make sure to place them apart, or you can plant them in rock gardens. Coral bells don’t need much water and can survive droughts, but you should still water them at least once a week.
Coral bells are suitable to plant in zones 4 to 9.

3. Knock Out Roses
Knockout roses are great as they can withstand extreme weather conditions without a problem. They’re disease-resistant and are known to be self-cleaning. However, they still need some care and protection.
Knockout roses are low maintenance. For the most part, the only thing to be mindful of when planting these bushes is the freezing cold. They need to be protected from extremely low temperatures to avoid their petals freezing.
To keep your roses looking fresh in bloom, you can also give them rose food every now and then. Other than that, these roses are pretty much plant-and-forget.
Knockout roses are hardy in zones 5 to 9.
4. Rock Cress
Rock cress is a colorful flower that suits any garden. It blooms in the spring in colors ranging from bright purple to pastel pink. Not only are these flowers colorful and resilient, but they’re also incredibly fragrant.
As the name suggests, rock cress can be grown in a rock garden. They require well-drained soil. Other than that, they don’t need any special care as they’re able to survive in tough conditions.
They’re great for Wisconsin gardens as they bloom in cooler conditions. Unlike most other flowers, rock cress has a shorter life span in warmer weather.

Delphiniums require more attention. They wouldn’t survive during sudden weather changes or in sunny dry weather. They also need stalking to stay upright.
Before planting delphiniums, you should be aware of their toxicity. All parts of the delphinium plant are toxic, not just the blooming flowers. This can be an advantage since deer and stray animals know to stay away from it and any neighboring plants.
