Just back last night from a short vacation in Wayanad, Kerala. Fresh from all the hibiscus research, it was the place to be. Wayanad, is hibiscus heaven.
Roads were lined with hibiscus bushes in full bloom, people's gardens had hibiscus fences, even our resort was home to several varieties. I must also mention the profusion of anthuriums, roses and dahlias to be found. But above all, the hibiscus was overwhelmingly present even used to mark borders of plantations. Some of the flowers were massive in size.
All of these pictures were taken in the garden of Wynberg Resorts ( where we stayed ) - Full Trip report with lot of pictures soon.
I have tried to identify some of these flowers with extensive googling. Corrections and additional info is most welcome.
Fringed Hibiscus (Hibiscus schizopetalus)
Also Called: Coral Hibiscus, Skeleton Hibiscus, Chinese Lantern, Japanese Lantern
Origin: Tropical East Africa
A weeping tree hibiscus. Grows rapidly and blooms freely. Flowers look like parachutes and can be recognized by the fringed and lacy petals which are bent backward. It has slender and gracefully curved stems. It will reach about 6 to 8 feet with a spread of 5 to 6 feet. It is a very fast grower. It gets very large in pots, so one needs to prune it often to keep a desired form. Pruning also helps to keep a abundance of flowers, since flower are formed on new wood. Blooms sporadically all year long.

Rose of Sharon
Rose of Sharon ( Hibiscus syriacus )
Rose of sharon bushes can get 8'-10' tall and have a spread of 4'-6'. However, some cultivars stay shorter (e.g., Hibiscus syriacus 'Minerva' reaches only 5'-8'). Blooms on rose of sharon can be white, red, lavender or light blue; some have double blooms. Most rose of sharon bushes bear small, deeply-lobed, light-green leaves (may vary according to cultivar).
