'Shalimaar' is suposed to be more cold hardy and it's a lovely tree.

I think some of the other forms are considered hardier a bit than 'Shalimar', though, which has been injured at -6F. That clone was not actually wild collected but grown from seed found in a famous garden in Srinagar. Others like 'Paktia' were especially selected from that cold mountainous area of Afghanistan for hardiness. I think 'Karl Fuchs' is considered among the hardiest of those, growing in central Michigan according to old threads here.

Great looking trees!

I have a few Deodar 'Kashmir'. I planted them this spring so they haven't seen winter yet. I'm hoping that they will do well here. I read somewhere that the deodar does better then Atlas and Lebanon cedar in heavy soils.
