Hibiscus Species, Swamp Hibiscus, North Cape Hibiscus

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 ag...Read Moreo. 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 will recover from pruning to several inches. I find it an excellant plant for training on a trellis or for an espalier. It is interesting in branching structure to train as a moderate sized "bonsai" plant.

Has bloomed year round...in winter as well if not fully exposed to sun, cold, and wind. Mostly a bloomer in warmer longer day length. Characteristically the flowers never open upward and outward but slightly downward. This makes it desirable to be grown with support to long stems in order to get a good view of the intense color of the center of the flower.

It's natural growth seems much like other bramble shrubs (some of the roses and blackberries and such). It's "sticky" stems and leaves seem to be an aid in growing through nearby taller plants otherwise becomes a low wide-spreading "bramble". Care taken in handling as the tiny spines can sometimes break of to become tiny slivers that are almost impossible to remove!
