Do you?
Two different plants, one with the pink, one without. Leaves are smooth and fairly thick and somewhat rubbery. The stems become woody towards the base of the cuttings. Flowers are insignificant (you can see them in the second picture). Apparently grows fast in bright light and responds well to pruning.

Acalypha wilkesiana? Some of the photos that come up in Google image search look similar, and some don't, but that'd be my guess.
I'm impressed! Looks right to me.
I was going to say it was a green, white tipped seratoleaf with a tendency towards pink. Close I guess.
That's where I was when I posted this 😉
