I bought this flower plant 2 days ago. But I don't know the name of the flower. Can anyone pls tell me the name?
Same story as the other plant you asked about - that's a bud and it will open when the time is right. Patience my friend... as to what it is, it looks a bit like Strelitzia reginae (Bird of Paradise plant) from the leaves - except the bud shape is wrong. If no one else knows what it is, please post another photo when the flower has opened.
Yes, got it, having seen the new photograph - it's Heliconia psittacorum 'Andromeda' and its not quite finished opening fully yet. It's a perennial native to the Caribbean and the north of South America, but also often listed as a Malaysian plant. The common name for this plant is Parrot Plant, though that also refers to other varieties of Heliconia.
