SP/VV has been attending the ASLA annual meeting in Boston - sorry for the diversion. That really looks like an Ilex integra to me - insofar as I know that species, which is only slightly. Any chance of images of the potential parent plants from the park? If this purloined seedling is related, then the buds/foliage will likely have affinity. Help us by providing that imagery. THEN: provide (maybe in another thread - Trees? Shrubs?) a list of those Ilex with which you have wuv.

Resin, Thank you very much!! I kept coming up with some type of douglas fir too when looking at picts on the net. But, I guess I always thought they were some kind of spruce so I wasn't sure what to think. Thanks Again!

Frequent branching producing many small sprays and lack of obvious winter burn damage to palest portions could indicate it is actually another golden form of that species. There are many.

Those are all names for the same species Nootka cypress. With some authorities these days wanting to revert to the combination Callitropsis nootkatensis. For instance this was the name chosen for the 2018 edition of the print publication Flora of the Pacific Northwest (University of Washington Press, Seattle). The specific crown shape of the specimen asked about here really has no bearing on its identification. Because it has been sheared into an artificial shape. Also the branching habit of Nootka cypress varies, with extra slender forms - representing a percentage of the material seen in cultivation - often being specific named horticultural selections. You can check the example shown here by seeing if it emits an unpleasant smell when handled and if the needles have pointed tips, that produce resistance when you try to run your fingers back along the spray. Also snipping a representative (hopefully unpruned) piece and taking it to where there are known Nootka cypresses - a retail garden center for instance - and comparing it up close with the foliage of those should make it apparent whether or not it is the same kind.
