Did it get caught in any of your extreme winter weather?
Otherwise, it appears to be badly missing the sun. Even if there is going to be a frost at night, tropicals will still benefit greatly if you can put them outside on a sunny day in the winter... just don't forget to bring them in at night! I've been doing the "tropical two-step" since December now, trying to put my tropicals outside any day that it is above 40F. I think tomorrow I will put them back outside (overnight) because the daily lows are not forecast to drop below 40F for the next ten days... and maybe not until next fall!
