I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
Some appropriate options include Leyland Cypress, 'Blue Atlas' Cedar, 'Soquel' Coast Redwood, and possibly Majestic Beauty Japanese Black Pine although its form is a bit more open and loose than the traditional Christmas tree shape.
Thanks for the question. Please stop in again soon!
