@Soph1e the funny thing is, I acquired this plant as a pale green cutting. My friend had it in a shady area of her house and I was baffled because it looked so unfamiliar. When she offered it to me I didn't even want it 'cause it looked so generic, ha ha. Then soon after I took care of it I placed it in a spot with more light and it started turning purple and I was like: "Hey, I totally know what this is!"
@misternatureboy it just goes to show what a difference the right conditions make. I took a cutting from one of my sister in law's tradescantias and mine looks totally different after moving it to my bathroom. The leaves have easily doubled in size and it's started to show it's variegated leaf pattern rather than being green.
This plant has grown so much since my friend gave me a few green cuttings last year. I came across the two pots (terra cotta on the left; plastic on the right) while walking B yesterday. Some jerk had dumped them along a hiking trail.
When a friend gave me cuttings of this plant--which she had growing indoors--they were green and unremarkable and I wasn't sure what species it was. Some months of exposure to sunlight later solved the mystery.
Thanks, @rlgravley79. Apparently, the common name "wandering Jew" applies to three Tradescantia species. This is #Tradescantiapallida (a.k.a. purple secretia, purple-heart, and purple queen) and you're referring to #Tradescantiazebrina. (The third is #Tradescantiafluminensis.)
