Funny story: We moved into this house in February and in one of the back bedrooms there was a dracaena, darker green but with red margins. It had been there in that back bedroom with only morning light and no water since the former owners had moved out the August before. The thing was to the ceiling, but hardly any foliage on its long tall canes, only at the top.
I started chopping and chopped all the canes down into 18" stalks. There were three canes on the mother plant and I must have had at least 12 little chopped stalks. I stuck them into a couple of buckets of potting soil and put them in a dimly lit corner till they started growing, then moved them more into the light. By Christmas I had 12 new plants and I gave them all as gifts because by then the mother plant had lots of new growth, too.
I still have the mother plant. It's still giving gifts, too, and has been chopped down many times over the years.
By the way, we moved here in '73 so the plant is older than that.
