what is my name

You think 10 metres is small!

:^)

Are they very thin leaves and a long stem....almost palmlike, if so maybe dracena

Need more info and clarification - 10 metres it can't be, that's tree sized - 1 metre is 39 inches, 10 centimetres is 4 inches. Shape of leaves would be useful to know. Only thing that springs to mind from current description (ignoring the size) are Coleus and Poinsettia - or Dracaena marginata, mentioned by Pamg

If it's 10cm, it could be an earth star or cryptanthus

I think 10 metres is a typo of some kind or Jack and the Beanstalk?
