A new introduction by Walters Gardens, ‘Mars Madness’ hardy hibiscus is out of this world with its unique foliage and flower combination. We love that the flowers of ‘Mars Madness’ are produced all over the plant, not just at the top, as is typical with other varieties. A late bloomer, this plant makes it easy to add stunning, saturated color to the summer garden.
