When summer heat sets in, Hardy Hibiscus bursts onto the scene with some of the biggest, boldest blooms in the garden—often as large as dinner plates! Despite their tropical looks, these stunners are native to the southeastern U.S. and are tough enough to thrive right here in North Texas.
Hardy Hibiscus, also known as rose mallow, is a cold-hardy perennial that dies back to the ground each winter and returns reliably each spring. It’s part of the mallow family and should not be confused with tropical hibiscus, which is frost-tender and grown here as an annual or indoor plant.
