Every summer many, many people purchase the Tropical Hibiscus to place on their patio, porch, or around their pool. While it is true that the Tropical Hibiscus is beautiful and really does lend a tropical look to the garden, it will die to the ground with the first frost unless you live in the sub-tropical states. And if you've ever tried overwintering one indoors, you know how difficult that can be!
Instead, consider our American Native Hibiscus varieties. There are several, and in my opinion they are much more beautiful than the Tropical Hibiscus. Our native hibiscus is an herbaceous perennial plant that grows to shrub size each summer.
Hibiscus coccineus has bright red star-shaped blooms all summer on tall stems. This native hibiscus is known by many common names, among which are Texas Star Hibiscus, Swamp Hibiscus, and Swamp Mallow. The Swamp Hibiscus loves consistently moist soil but grows well in my garden with only weekly waterings. Hibiscus coccineus is beautiful even when not in bloom, having reddish-tinged green leaves shaped like maple leaves. (Some visitors have claimed it looks like marijuana, but I can't say for sure, since I've never seen a marijuana plant. Perhaps they're telling on themselves!)
'Very spectacular' is the best description for Hibiscus moscheutos or Swamp Mallow. Blooms are the size of a dinnerplate! (See the photo above, one of the plants in our garden!) Hybridizers have developed many types and colors, but all are beautiful and any one would be a show piece in your garden.
The native hibiscus is so easy to grow that it would be a shame not to have some. H. coccineus is hardy as cold as USDA Zone 6 and H. moscheutos is happy as cold as USDA Zone 4! Wow! They are deciduous plants but will return in May each year with no special care.
