My hibiscus survived last winter, unprotected. (otter tail county). I was totally surprised when two stems came up late spring and it flowered about 12 or so blossoms. This fall I plan to cover it with straw.
Therefore, I am thinking some of these hardier hibiscus WILL survive in MN, contrary to what is stated on your site. Wish I had kept the name/info about this particular plant.
