Help ID my Dracaena/Cordyline
We've had a Dracaena or possibly a Cordyline as a houseplant for about as long as I can remember. As far as I can recall, it has never fruited or flowers, but puts up prolific shoots. I think I have narrowed it down, due to leaf width and shade, to Dracaena draco, Dracaena cinnabari, Cordyline australis (previously Dracaena australis) and Cordyline stricta (previously Dracaena stricta), however I could be off here. A picture is below and, I can take more if it would be helpful. Thanks for any help.
