The (Afican) Swamp Hibiscus is what seems appropriate for me to call it... as that is where it was collected by Gary Hammer 20+ years ago. I have seed grown plants from the original one purchased at Gary Hammer's retail Desert To Jungle Nursery (L.A. area in CA) I also want to remind people that H. coccinea of SE USA is also called the Swamp Hibiscus...this can be confusing using just common names!

This hibiscus is quite easy to grow and will reseed to some extent. Contrary to some opinions I have found it to be adaptable to moderately dry conditions where leaves remain small and growth is not as lush. It is ever-green to partially ever-green in my central San Diego area (92105). It thrives with extra pruning especially early winter here. Has never died to the ground but wi... read more

Along the St. John's river in Central Florida these plants grow in abundance. Most have varigated leaves of silver and green. I suppose they need plenty of moisture to grow in a green house or in a yard.

H. diversifolius is native to S. Australia (i.e., grows in a temperate zone), in Hibiscus Section Furcaria, most of which are also hardy perennial.

Hibiscus diversifolious - aka Swamp Hibiscus. A native of tropical Africa and Asia but has been introduced to Central and South America. A small shrub to 3 4 feet, it is often grown as an annual, but in pots as a perennial for cultivation in a warm house. The plant is listed as Zone 10 (European). Care is needed when handling the plant as the stems, leaves, and particularly the seed pods, are covered in tiny thorns. The flowers are solitary, cream or pale yellow with a maroon centre (see picture). Easy to raise from seed or cuttings sown under glass in Spring.
