That's not Dracaena draco - the internodal stem growth between the leaves is much too much. Dracaena draco basically has a stemless rosette for the first 3 years or so; here's some 2-year old seedlings, seed from Tenerife.
I do believe they are I started them in winter very stringy but have in greenhouse now are starting to beef up now doing much better
Still have a way to go but still lots of greenhouse time my problem was not only was it winter but got overwhelmed must of had 50 + germinate & was working on about a dozen others did not give them the attention they needed
