One of the most enjoyable plants I have in my garden. They constantly bloom. The only setback is that they get infested with mealybug farmed by ants and that if you forget to water - they tend to wither and may not recover back from the former glory.
The good thing is that they resurrect back during the end of the year during the raining season and they just sprout everywhere - wherever the seeds had sprouted. And so, to say this plant had totally died from the garden - may not be true as they do come back again.
