Tropical flowers for colder climates

Name: Swamp rose mallow (Hibiscus moscheutos and cvs.)
Zones: 5 to 9
Size: Up to 6 feet tall and 2 to 3 feet wide
Conditions: Full sun; prefers fertile, moist soil but will adapt to a variety of conditions

The colorful foliage and large flowers of swamp rose mallow provide a spectacular late- summer show. It works best in combination with other tall perennials and ornamental grasses. The plant ('Lord Baltimore', pictured) is slow to emerge in spring, requiring a gardener's patience. It's best to leave the dead stalks in place over winter to remind you of their location in the garden once spring arrives.
