My gosh,you are doing a wonderful job. Yes, they are tuberous and usually need a rest every year after bloom. Ignore the stalks, let them fall if they want to. The little pinkbuds are the new stems trying to start another season, they will need some warmth and good light from now on to repeat their bloom cycle. Whatever you were doing, you were doing well.I think I should be asking you for lessons.

WOW, I hope mine do so well. I just bought a "Nonstop Mocca Yellow" and a Nonstop Mocca Scarlet. I have mine outside on the shaded patio.

Oh thank you... the window faces east but how my house is situated, it's weird.. So it does get full sun in the morning only. Does it need sun all day?

It's looking pitiful though, heh. so in the winter I'm supposed to put the pot in the garage in cold temperature? I left it on my window sill year round.

Here is a link that might be useful:

Well, in theory the tuberhybrida need good light, and that is what they usually get when grown outside. If it continues to thrive, see if you can't find an outdoor location with good East or sun. I don't think it has a tuber if it has been growing all this time, so I wouldn't worry about storage until fall if it is still around. I think eventually it will have to rest. But, I'm no authority. Why not buy another Non-Stop and see how it does, that 'mocca' variety sounds interesting.
