I found this what I assume to be tradescantia zebrina last winter as a little stem with three leaves laying on the ground. It has turned into one of my favorite plants over the last year!
Apologies for being deceiving! Its planter is about a foot and a half off of the table using a stand. It is inside for the winter and I was trying to keep it away from my dogs! Aside from the stems on top standing up about 8 inches, the rest of that is spilling over the side of the planter.
I think its a combination of getting a lot of sun outside this summer and me snipping off a strand once it gets to a certain length so that a new one can grow.
