Just as California gardeners love their year-round sunshine, Wisconsin gardeners hold their winter snow in high esteem. It’s a natural mulch, they will tell you, protecting the roots of flowers (Wisconsin Online). All perennial flowers go dormant, and then make their reappearance at the appropriate time. Wisconsin perennials wait out the winter beneath the snow and burst into bloom during all three of the remaining seasons.
