My Two -Faced Plant

I bought a plant some time back in an attempt to make my house look a bit more 'organic.' After a week, I bet the plant was regretting that it ever met me...

Argh... someone please put me out of my misery!

The leaves were drooping, the flowers didn't look like flowers anymore and if you listen closely I think it was trying to commit suicide. A discussion with the Mrs led to us watering it more, changing its soil and moving it to a different location (cause we thought that maybe...just maybe...the conditions were to harsh in that particular spot) but it still looked the same. And no, I was not about to start talking to the plant in a last ditch attempt to show some TLC.

Now normally I don't notice the plant much in the morning as I normally rush to get to work but a while back, I noticed that it seems to be looking better in the morning.

Night

Hmmmmm....so its just circadian rhythm at work after all. However, the flowers are still non-existent. Any suggestions? Fertilisers?
