Perennial plants are a critical component of any successful garden. While planting new and exciting annuals each season can be fun, perennials serve as staples that keep your landscaping grounded. However, every part of the country is different regarding what perennial plants are the best. The most ideal perennial plants for Minnesota must stand up to extreme weather and often not ideal conditions.
So, what are the top perennials for Minnesota? We can learn a little more about the climate and which Minnesota perennials are the most suitable for this climate zone.
What Are Perennials?
Perennial plants are plants that grow and live for more than two seasons. These plants establish their roots in the ground, and while their flowers or even the whole plant may die and wither during the winter, the roots survive, and the plant regrows each spring season. Perennials are most often contrasted with annual plants, which live for just one season. After the summer, annual plants will die. You remove them with the rest of the weeds in the spring and plant new ones.
Many people prefer to plant perennials for Minnesota because they are low-maintenance perennials Minnesota residents can grow. Some Minnesota perennials will go through their life cycle all on their own, while other perennial plants Minnesota offers only require minimal trimming or pruning to keep them growing back fuller each year.
When Do Perennials Grow?
Each perennial plant will differ slightly in terms of care, maintenance, and growing habits, but most perennial plants for Minnesota come out of dormancy in the spring. Some Minnesota perennials will follow the patterns of the weather, blooming as soon as it starts to warm up outside.
Other perennials for Minnesota wait until the summer to begin blooming. Certain plants may only bloom once in the spring, while others will continue to bloom until the fall cools the weather down.
