Question
hi,my  drac.marginata is at least 51 yrs old now,only been repotted once,never trimmed and still growing,is this normal for a plant to live this long

Answer
Shaun,

It is unusual but they can live to be over 100 years old with proper care. I would love to see a picture. You must be pruning it regularly or it would be outgrowing your home. Congratulations on giving it such wonderful care and I hope you and it live another 50 + years.
Good luck!
