There are so many species and varieties...
Yes, this is really a problem when one has to identify young junipers.
I will not pretend I know but a wild guess: juniperus scopulorum
Thanks Auk, I'll take a look (Rocky Mountain Juniper, right?)
Where was it collected?
We have a range of mountains two hours west of São Paulo , 2.000m high; the microclimate over there is cold and european like. So one can find all sorts of conifers thriving there, and some nurseries sell a lot of pines and junipers for the properties around.
