Try the conifer forum or a regional forum found on the Gardenwed forums page.

I don't know if many Colorado folks post on this forum.

I second Rhodium's suggestion that you try the Conifer forum and the Tree forum for suggestions.

Research is what you need. Go to a good local nursery. Observe what neighbors are choosing. Read books on Colorado plants. Call your county extension and pick the brain of their on-call Master Gardener, if that program is supported where you are. Someone may have an answer that works.

There's one plant that I know of that might work for the cypress look. I say this because that's what someone else wanted and they were located in Michigan, which is a heavy snow state. The problem is that this cultivar is very, very slow growing. It's usually found at about 2 ft wide / 5 ft tall. The person I read about found and ordered 10 foot specimens.

The conifer is Thuja occidentalis 'Degroot's Spire'. I don't have any idea whether it's available where you are or where you go to get taller ones.

Degroots is good, but a Taylor juniper is an even better choice. Taylor is a selection of the eastern red cedar, J. virginiana. It is supremely adapted to the midwest plains - and should thrive on the front range. It is the closest thing to an Italian cypress that we can grow successfully..
