Grow up my flower

I bought a flower. A red-yellow kekwa flower. This my third flower I bought here. After 1st flower kinda dead but I wouldn't give up on my flower. I take necessary steps to ensure its survivor because my friend and his partner said to me that before I back to kl, please give the flower to them to take care. Now the leaf already green and the only thing I want to see is a purple kekwa flower. I to see my flower grow. Need to take a good care of it.
