They grew on a flower spike that I had cut and put in water, otherwise, I could do what you suggested. I trimmed a lot of old, leggy flower spikes and since they still had a couple of flowers, I stuck them in water, and guess what, babies all over the place. I have some in baby food jars with a little bit of water and put a little moss in the bottom of each, keeps them from tipping over. I was thinking about dropping a granule or two of magnesium in there, Epsom salts. A master gardener friend of mine says magnesium helps root formation.
