Picea omorika (common name Serbian spruce) is from southeatern Europe, and is hardy to Zone 3b.
Picea omorika ‘Blue Sky’
It is supposed to be a narrow bluish pillar reach 2 m in 10 years; sounds really great for garden use.
Picea omorika ‘Gunter’
Picea omorika ‘Mount Nemo’ (GC)
I imported some Picea omorika x breweriana from the US more than 15 years ago as one gallon stock. All of of them cannot stand straight without heavy staking except one which stands straight as a very narrow column (approx. 1 m spread) and is probably 8-10 m tall; a perfect tree for city garden. It was crowded by other trees and slowly losing its dense structure on one side. All the staked ones had since died one after another.
My understanding is the existent of the hybrid Picea omorika x breweriana has not been confirmed by botanical academics. With the help of the experts on the Conifer Forum in GardenWeb, it was identified through the cones collected from the tree that this is an omorika and not a hybrid. However, the distinct ‘extra’ pendula characteristic suggests that it could be a chance seedling or sport different from ‘regular’ omorika. I temporarily give it an unique identity for recording in my database. The (GC) designation in the name means that it is a name I assigned.
Picea omorika ‘Pendula Bruns’
This is a popular weeping spruce among the conifer collectors.
Picea omorika ‘Pimoko’
It is another dense mound shape omorikaquite similar to ‘Gunter’.
