Chinese Lantern Flower

I was searching for a climbing plant in the nursery and saw this bright red flowers and couldnt help myself but took home with me.
It is called Chinese Lantern flower.
I planted it in a pot behind the kitchen and hoping that it will fill up the wall grill.

I love looking at it especially when the sun shines on them and seeing the shadows and reflections of the leaves and flowers.

But it didnt last long.The flower colours fade away and the leaves became yellowish.

I suspected it was because they didnt get enough sunlight there and also the pot was not big enough for it to grow fatter.

So I transfered it to the front where my bunga telang used to be.(Yeah the bunga telang was so out of controlled that I decided to pull it out).
I am hoping for it to give me bright red lanterns one day.

So far I only see these...
