The Hardy Hibiscus is not the fussy tropical houseplants, but a tough, hardy shrub that lights up gardens as far north as Zone 4 (Minnesota/Wisconsin/North Dakota) with flowers up to 12 inches across!


While it is similar to its tropical cousin that many of us may grow as a houseplant, hardy hibiscus is able to withstand temperatures as low as –30°F, as it is primarily a hybrid of two North American natives: swamp rose mallow (Zones 5–9) and smooth rose mallow (Zones 4–9).


Hardy hibiscus can appear shrublike, but it primarily performs as a die-back perennial that is often slow to wake up in the spring, sometimes convincing Northern Plains gardeners that the plant died the previous winter. However, once the soil warms and the plants begin to grow in late May to early June, you will soon be greeted by a plant that grows an inch a day and matures to 5 to 6 feet or taller by late summer, covered in tropical-looking blooms the size of dinner plates.


To grow hardy hibiscus successfully, choose a site that is in full sun, receives consistent moisture, and has enough room for the plant to grow. Because it wakes up so slowly in spring, consider planting it with spring-blooming bulbs that will be fading just as hardy hibiscus awakens. Before you know it, you too will be asked by stunned onlookers if that really is a tropical hibiscus growing in your garden!
