Wisconsin Hardy Hibiscus - Summer Showstoppers!
First these hibiscus are perennials. That's right they come back yard after year. Second these plants can trace their heritage back to primarily Hibiscus moscheutos a species native to the central and eastern regions of the United States. They are hardy from zones 4-9 and dieback to the ground each year.
They perform best with consistent watering, particularly if they have been recently transplanted. If your Hibiscus is losing its lowest leaves, or aborting buds, you may need to up the aqua! They are late to break in spring. They're not dead! They may not show signs of life until June. After that they grow fast, very fast. Lastly plant them in the sun.
