What variety of Yucca is it? There are hardy ones but all need lots of grit added to the planting hole to make it free draining and a sheltered sunny spot. If it is a standard house plant then you can put it outside in summer but it will die in winter, esp long winters like this year.

Thanks for your prompt reply. Looks like it will have to stay indoors.

Kildermorie is right but i have a suggestion...if its too tall and you would like to keep it you could alway chop it.....sounds drastic. but if you saw it off about half way down the trunk it will 'fingers crossed'...regrow from the stump.
