They do not look like zebrina to me. The patterning is not right and there is too much red in the pseudostem. It is difficult to say exactly what it is though because there are many different hybrids out there as well. Plus ssp. zebrina is not the only wild variety with this type of coloration on the leaves, although these plants do not appear to be a wild type anyways. Pete's looks more like something Cavendish almost, not zebrina at all. To me, they look more like a Rhodochlamys/zebrina hybrid, similar to 'Bordelon' but not necessarily that particular variety as there are a few different similar ones out there. As is the case most of the time, for this one I wouldnt rely on any positive ID without a flower (but I still don't think its zebrina!
)
