This is a Dracena Marginata, good for low light, keep on dryish side and if
they get too tall, just cut them off where you want to and new leaf buds
will form, then you can put the top part in a plant pot ( of course with
potting soil) and it will grow also! I have so many around my house outside
(Florida) cause everytime I trim them, I put the top into the ground and it
grows!
