It does look like Bolivian Jew as well, doesn't it? I suspect the care during winter would be the same as for Gibasis. What color are the blooms for Bolivian Jew? Tiffany's advice for taking cuttings would be good for either one as well. I have Gibasis geniculata and rooted cuttings have been the only plants that I've managed to grow well and attractively. My main container of it manages to only look nice for about one day out of 365 and ratty the other 364 days
. But the cuttings stuck in and around other plants, mainly daylilies, have been superlative - and then they freeze. Oh well. I don't water the Gibasis or anything else very much during the winter months.
