Lawzy! I don't know, Tiffany. That was Cheryl that suggested Bolivian Jew. I just looked at that in the database and saw that the foliage looked similar. My guess was based as much on the stems and leaf size combination as anything else. The length between leaf joints reminded me of Gibasis, but purple backed leaves and the bloom would go a lot further to identifying it. It was just my best guess which is why I used a database photo showing the blooms. Most tradescantia blooms that I've seen have mostly been sort of pinkish. Searching for Bolivian Jew did turn up Callisian repens and I've seen it (I think), but haven't grown it that I recall. I guess what I grow could be something else, but it was called 'Bridal Veil' when I got it. At the same time I was told it was a Wandering Jew. Common names can really mess things up! It took me a little while to look it up and decide what I grow was Gibasis geniculata and not Tradescantia of any sort. Obviously they are closely related. I have found the Gibasis to be different to manage than any Tradescantia I've grown. I haven't mastered growing it well yet. The plant I have does have strongly purple backed leaves and lots of white blooms that are the reason it was sold with the name 'Bridal Veil', I'm sure. The stems get purpleish too. If Kiss knows some further details from when it was growing outside of the basement, then some options could be eliminated. Your photos sure help in distinguishing between some of those options.
