I’ve got a new favorite blue conifer, in a climate where most blue conifers fear to tread. Cedrus atlantica ‘Horstmann’ is a 1970’s selection from Germany’s Horstmann’s Nursery, that forms a very compact specimen. Our seven year old plant has reached 7′ tall x 5′ wide, without any type of opressive control. Typical blue Atlas Ceder, which hails from North Africa’s Atlas Mountains, has a much more open and faster growth habit, reaching 100′ at maturity. At only 1′ of growth per year, Cedrus ‘Horstmann’ should reach 20′ tall in two decades.

Full sun? Great looking tree, but as you note, very difficult to grow similar trees here in the humid south!
Yes, full sun, all day.
