What I've read is that it is a somewhat narrow spire, with maybe one central leader, so it doesn't sound very wide. 20-30 years down the road...?

I planted a hedge of these back in 2002. They've probably grown about a foot a year and are currently about 8 feet tall, and 3 to 3-1/2 feet wide at their widest part (they are sort of pyramid shaped, so wider near the bottom.)

They are still dense, but have more of a "loose" appearance than other cultivars like 'smargd' or 'brandon'. Sort of a feathery look near the top. They take pruning well though and here in a sheltered spot in zone 3 suffer just a bit of winter damage some years. I think I planted my plants about 2-1/2 or 3 feet apart for a hedge. To me, some years the new growth almost appears a bit golden or pinkish on the branch ends. It's a nice shade of green.

P.S. when I first bought mine I too had trouble finding information on this cultivar. Since it's from Europe and quite popular, if you do a search you will find lots of nursery websites but in German or other languages.

Thanks everyone, I think it will do. My German is pretty much limited to "Wo ist der bahnhof" and "Eine grosse bier, bitte."
