This plant reproduces by dropping many tiny versions of itself from the edges of its leaves. Larger ones will produce pinkish downward pointing tubular flowers that are about an inch long and appear in groups of three. I have seen them growing in very tiny amounts of sand on metal stairs, in soil, or in the case of my sample a glass of water with some light amount of Humax and algae solution. Sorry for the poor image quality, I don't have my digital camera with me. Thanks in advance for helping me ID this plant!
Note: seriously invasive in subtropical areas. Don't let the plantlets dropping off the leaves get a foothold outdoors in Florida!
K. daigremontiana is toxic and as pointed out extremely invasive. I found the parent of all these monsters hidden behind a bromeliad that probably came from south Florida and destroyed it along with about 100 of its offspring.. I'm fascinated by the reproductive strategy but I don't want poor animals dying from it.
