Wow. I bought this hardy hibiscus at a late season sale in the fall of 2013, and then we had a very cold winter with many days below zero. There was no sign of life from the plant in the spring. Then in summer, it erupted. It is covered with buds, and every day a couple of impossibly huge, deep red blooms turn the corner of my vegetable garden into a tropical paradise. It is clearly tough enough for Minneapolis

Super dark red color on this hardy hibiscus makes it stand out from many feet away. And it doesn't require the TLC that tropicals hibiscus do. What's not to love about this low maint. plant. I don't know if it produces seeds, I sure hope so. Would love to have a big patch of this beauty growing in my garden.
