I "adopted" this plant after a family member moved, but I'm not sure what it is (see photo). My wife thought it might be a Wandering Jew, but searching Google Images for that seems to show primarily plants with variegated leaves, or those where the tops of the leaves are purple and the bottoms green like "Purple Heart"; this is the opposite with green on top and purple underneath. It doesn't look like a plant that would grow upright, but more like a vine.
Hoping someone might be able to identify this.
