What The Heck Is Going On???!!!

The Portulaca molokiniensis on the left has always had a mind of it's own (figuratively speaking), but look what it is doing just days after it's transplant... That is not a small movement. And if I didn't know better, I'd say someone steamed it and bent it into that shape. I'll try to relocate the box to give it more light - that's all I can come up with why it MOVED SO MUCH in so little time... The good news is there are offsets forming on so of the exposed stem.
