Dwarf conifers for Colorado - Denver Metro area
Looking for small conifers for my small yard. I seem to be pretty good at killing various conifers that I have tried, though I have had good luck with a Pinus banksiana 'Uncle Fogy' that has been growing happily in my back yard for about 10 years, (it has eastern exposure - managed to kill one that I planted in my front yard with western exposure,) several varieties of aborvitae, a Korean fir - Abies koreana 'Horstmann's Silberlocke' - that has been growing nicely for about 3 or 4 years, also in my back yard. I have killed other firs, as well as at least two Picea pungens 'St. Mary's Broom.'
Junipers seem to do well in this area, too, though I am not fond of the "ground cover/foundation cover" sort that seem to be popular here. I do have at least two upright junipers that are doing well - one was growing here before I moved in about 20 years ago, another is an unknown cultivar that I got from a nursery in Boulder - they didn't know what it was, either.
I am looking for recommendations for relatively dwarf conifers - 8-10' in height, with a relatively narrow spread - that will do well in clay soil, lots of intense sun light, and somewhat dry conditions. Impossible??
