i had never seen trandescantia zebrina aka wandering jew bloom. then, a few months ago, someone posted a pic of the blooms on theirs.
well, today, i was at ellie's and went to get some cuttings that i had left in a vase there, and LOOK
these cuttings had been in that vase nearly a month, had not been taken care of, other that more water added (the water was PEEEEEEWWWWW stinky), did not seem to have any roots to speak of, and had had the heat turned way down because there was a busted water line and my daughter had to move out.
i told her that i've decided that the key to getting a wandering jew to bloom was cool temps, lots of water, and general stress beyond that.
