Hibiscus moscheutos Rose Swamp Mallow - A Perennial Flower For Your Garden © 2007Visit Our Online Store.For Perennials and Perennial Seed |
Hibiscus moscheutos Family - Malvaceae - Mallow Swamp Mallow This perennial is a giant, growing to eight feet tall under the right conditions. It gets around four feet in my garden. The flowers are tremendous, also, up to ten inches in diameter. Swamp Rose Mallow is hardy to USDA Zone 5 - 9, and flowers abundantly from mid July until around Labor Day. Hibiscus moscheutos is native to the Eastern United States, where it grows in marshland. It prefers rich, moist soils and full to partial sun. Rose Mallow is the largest perennial flower in the garden, so give it plenty of space. It is suitable as a quick, summer only hedge as it dies down to the ground each winter and grows quickly in the early summer. It emerges late, usually after just about everything else has come out. The only pest which seems to trouble Rose Mallow are the Japanese Beetles which feed on the blossoms and leaves. But the Beetle population seems to have declined in recent years and the ample blossoms usually don’t suffer too much for the damage. Hibiscus moscheutos is best propagated from spring divisions or summer cuttings. The biggest problem in our southern Indiana garden is that the plants flop over and need to be tied up in order to keep them from crowding out nearby perennials. |
