I'm no expert, but I'll share my experience. They root from cuttings fairly readily, so you might go ahead and take a piece off a runner and try. All Episcias aren't created equal. Some with the bright colored foliage (e.g. pink leaves) can be difficult plants to manage and keep alive. But it's variable from one to another. I grew this green one outside all summer of 2013.
The pink leaved Episcia and the silver veined leaf Episcia could not manage outdoors. The slightest damage from an insect or getting torn sent them into collapse mode. They do fine inside.
My Episcias are not tolerant of a wide range of temperature and they prefer humidity. Temps under 50 killed the green one, but they also clearly suffer when the temp gets too warm. I'd say they prefer 70-85F with considerable humidity and they prefer to be kept evenly moist. These last are hard inside, but they look good most of the time if I don't forget them for too long. There are some Episcias with beautiful foliage that I think can only be grown in terrarium conditions. Good luck.
