They are 4 cultivars, still with "temporary" names, because they are new one: two of them are from our nursery owner Kiril Donov, selected by him, so I call them " Donov 1" and two. The biggest one on the photos. Two another one are still in pots - I decided to grow them a year that way, couse they're still too little(in April when I take them, they were 30 sm(~1 ft) tall. You can see one of them here in the brown pot:

They are from some French nursery, Donov said, located on 800 meters above sea level and not so close to the Mediterane or the ocean(which means not so mild winters).
They grow very well (this from last photo is already twice taller and more) and I plane to test him in open ground next year, but another 4 (Donov 1 and 2) already in OG will be tested this winter. With different protection, most of them - passive(no heating). Depends from winter - if we have another one February 2012(HOPE NO!!

) they surely will die (that part above snow cover), but if the last one - 2012/13 they surely will survive with no protection.
About another your question: In the southern part of the country many enthusiasts grow different cultivars of olives many years and even decades, some of them are bigger trees and they harvest from them olives for own use

But till last years most of that trees was situated on Black Sea cost or in non-inversion hill parts of the south of the country, 8a zone and in sheltered locations in the yards. So, my experiment is maybe one of the first in the most continental northern part of the Balkan. So, propose it will be interesting.
Another notice: cultivars I described above are the most tested and proved from that nurceryman - 3 the most hardy from tens of tested last 2 decades. They grow without any trouble and they survived even historically 60-year-most-hard last February(2012) with NO protection in the south of country. So, next winters they will try to make the next step in 7a zone and wi shall see how that will work.

Thanks for attention and have a niece day! Ivo
