The tropical hibiscus (Hibiscus Rose-sinensis) attracts hummingbirds and butterflies with its large, delicate flowers. Each blossom can grow up to 6 inches wide for a spectacular show. They work well as houseplants and outdoor plants (in select areas).

Hibiscus plants bloom almost year-round as long as they receive the right care. The Alabama A&M Cooperative Extension System notes that plants go dormant in the winter. Expect colorful, papery flowers the other three seasons.
Most hibiscus flowers last for only one day, according to the University of Minnesota Extension. After that, they close up and fall off naturally.
Hibiscus is naturally a tropical flower and is only hardy in zones 9 and 10. Gardeners in other states should grow hibiscus in containers and keep them indoors when the temperatures get cold to avoid killing the plant.
