(From Singapore) Didn't actually know the name of this flower. I spotted it alongside a busy street admist some bushes. Its contrast of striking red & green with its plastic like petals caught my attention. It actually is quite small in size, approximate about 2 segment of a Asian Lady's finger-pad. Saw this plant again somewhere else in the city too. They just grow out of the bushes along streets. No special care of being taken of them. Only the natural sun & rain.
