The Hibiscus plants are locally known throughout the Philippines as the Gumamela.
Though this plant has short-lived but continuing blooms, the scent-less Gumamela is one of the most widely cultivated of flowers here in my hometown.
Presently, I have eleven shrubs of Hibiscus rosa-sinensis along my fence.
Eight of my Gumamela shrubs are potted while three of them are planted on the ground. Moreover, nine of these flowering shrubs are hosts to some of my Dendrobium orchids.
These plants bloom throughout the year for I placed them in the area of my garden where they get a few hours of direct sun every day. I’ve noticed that the bloom life of these flowers are about 2-3 days, with a succession of blooms that last for months.
More often, my Hibiscus plants produce gorgeous flowers in vibrant color in red, white, pink, yellow, peach, orange and purple. So for years, I’ve enjoyed their ruffled and trumpet-shaped blooms.
To get more blooms, the rule of the thumb is pinch and prune. Since I don’t want a huge shrub in my garden, I prune my Gumamelas when necessary. Pinching their growing tips also helps them to branch out. I’ve planted the cuttings in black bags filled with sandy-loam soil.
Moreover, these plant are not only ornamental but medicinal as well. Hibiscus rosa-sinensis is one of the plants listed on Philippine herbs. http://www.stuartxchange.org/Gumamela.html
