conifer Goldcrest

Any idea how tall this conifer might grow to be?

The full grown height of this is 15m Dorjac. I've had one in a pot for around 4 years. It survives on pure neglect. In four years it's put on around 3ft being restricted.

£ 2.50 what a bargain I have to pay £7-9 for the same plant.
I find they grow quite quickly but dont get so wide as others do.

A very pretty conifer to be sure. 15 metres is a bit scary in the ground Scottish! My brother grew one that looked the same in my Gran's old shallow 'slopstone' sink. It was there for years and always looked good too.
