I have what is called a corn plant, which I think is actually a dracaena of some sort. It has a long bare wide stalk with several green variegated leaves only at the top. When I repotted it a few months ago, it had absolutely no roots. It was just like a sawed-off log at the bottom. The other day my cat knocked it over and I saw that it still has no root system. The plant does grow all the time and seems pretty healthy. Are these plants not supposed to have roots? I know that they are actually the tops of other plants that have been cut but I would have expected to see it grow its own roots by now. Thanks.
