This particular one is known as a Rose Begonia also known as Tuberose Begonia. I often noticed this sold during the festive season - normally brought from Cameron Highlands.
I had few bad experiences with this and also checked with few of my gardener's friends who tells me the same thing - that this one is very difficult to cultivate in lowland climate. I believe this one do require cold climate cycle for it to go dormant and regenerate especially like in a temperate climate.
I realized that many people who favor this particular one treat this plant as a cut flower plant - keep and maintain them for few weeks until the flowers are spend. However, I know the plant will survive but slowly will start dropping off all it's leaves and eventually the bare stalks will start to turn yellow and wither away.
There is however, a tuber underneath it and may require it to go through some cold handling - suppose placing the tuber in the fridge for 3-4 months and re-plant the tuber back for the next season. This appear to be like too much work and may or may not be successful - Just my thoughts.
I'm still wondering how are they cultivating these cold temperate plants here in Cameron Highlands, especially these and a few other plants like Fuchsias, Dahlias and Roses. They don't last very long in these hot and dry lowland climate and truly they become sad looking when they start withering away in the heat.
I may got my facts wrong in this particular one but I have yet to come across anyone who had claimed to have a success story in cultivating this one.
