Perennial hibiscus in Minnesota? You betcha! This is a perennial for the back of the perennial border. Even small perennial gardens can have a hardy hibiscus. Growing to heights of 3′-4′ tall – it will wake up quite late in the spring – making you think you’ve lost it due to a cold winter. My hibiscus has been in the far side of our garden for several years now. This past spring, I thought it was a goner since we had little snow and I thought it had froze too hard. However, early June it sprang up and is now filled with many blossoms. The blossoms? Dinner plate size.
Hibiscus like full sun to partial sun/shade. Provide adequate moisture. In the fall, after it has gone dormant, prune down to 2′-3′ and apply a heavy layer of shredded mulch over the top of the crown to “tuck it in” for a long winter’s nap. In mid-April, pull the mulch away and wait for it to wake up for the growing season. Let your hardy Hibiscus become the summer “star” in your perennial garden!
