I got the plant in the picture:
Which plant is it?
I think it's Dracaena marginata
I have one in my garden, I cut it off at ground level because it was in the way for painting the house. It grew back. The bits I cut off got thrown in an old broken bucket with some crappy dirt in a place that gets a bit of sun and they're still alive 5 years later. Basically if it is what I think it is then it's tough as old boots and looks pretty decent in the process. Cut it back if it gets too long and leggy.
