I can never have enough look at a flower with translucent soft pink petals that perfectly overlap each other.
This should be an allamanda. It is a common household ornamental “pet” flower in my country. It is easy to find seeds of allamanda, and easy to get them to grow well.
I have tried to verify the identity of this flower through searches, so I hope I am right. But feel free to comment if I am wrong about the name.
